God & BeliefStory
Can someone love science and still believe in God?
Many scientists believe in God and many do not, so here is what the surveys show, what science can and cannot say about God, and where both sides meet.
THE QUESTION LIBRARY GOD & BELIEF
Doubt is common among people who stay in their faith and people who leave it, so here is what surveys, scriptures and research say, and how to talk about it at home.

THE SHORT ANSWER
Yes. Questioning what you were taught is common and human, and many religious traditions make room for honest doubt. In a large 2023–24 Pew survey, 35% of U.S. adults had switched from the religious identity they grew up with, and many believers are not fully sure either. Some people work through their questions and stay in their faith, some move to a different one, and some leave religion. Where your questions lead is yours to decide.
WHERE THE EVIDENCE STANDS
WHAT WE DON’T KNOW YET
Most research on doubt comes from U.S. Christians, often older adults, so it may not fit everyone. Studies that link doubt with distress cannot show which one causes the other. Nobody can predict where one person’s questions will lead.
WHAT WOULD CHANGE THIS ANSWER
Studies that follow people of many faiths for many years could show more clearly when questioning helps and when it hurts. New Pew surveys could change the numbers on this page.
Yes. Asking hard questions about what you were taught is common and human, and having questions does not make you a bad person. Many religious traditions make room for honest doubt. This page will not tell you where your questions should lead. That part is yours.
People come to this question in many ways. A teaching that once felt solid stops making sense. A loss or an injustice shakes an answer you trusted. You meet good people who believe something else, or nothing at all. Or you simply grow up and want to understand for yourself what you once took on trust. Often the hardest part is not the question itself. It is the fear of what it could mean for your family and your place in your community.
You are far from alone. In the Pew Research Center’s 2023–24 Religious Landscape Study, 35% of U.S. adults had switched from the religious identity they grew up with. Most Americans, 56%, still identify with the religion they were raised in. And belief does not always mean certainty: 83% of U.S. adults say they believe in God or a universal spirit, but only 54% hold that belief with absolute certainty.
Questioning also does not decide the ending. Some people work through their doubts and stay in their faith. Some move to a different faith. Some leave religion and build meaning in other ways. And some keep living with open questions. Thoughtful people take every one of these paths.
Below you will find what traditions say about doubt, what research says about how questioning affects people, and some kind, practical ideas for talking with family. If your questions come with fear, shame or real conflict at home, you deserve support while you think.
Very common. Pew’s 2023–24 Religious Landscape Study, a survey of 36,908 U.S. adults, found that 35% had switched from their childhood religious identity. That count includes people who left a religion, people who joined a different one, and people raised with no religion who later joined one. Pew does not count a move from one Protestant church family to another, such as Methodist to Baptist, as switching.
In a follow-up survey of 8,937 adults in May 2025, Pew asked people why they stayed or left. Among those who still hold their childhood religion, 64% said believing its teachings was an extremely or very important reason, 61% said it meets their spiritual needs, and 56% said it gives their life meaning. Among those who left, the most common reasons were that they stopped believing the teachings (46%), that religion was not important in their life (38%), and that they gradually drifted away (38%). Of people who switched to a different religion, 48% said they felt “called to a new faith.”
These changes tend to happen young. Of those who switched, 85% did so by age 30. Childhood experience matters too. Among people raised in a religion who had a mostly positive experience with it, 84% still identify with it. Among those with a mostly negative experience, 69% now have no religion. Pew notes that the link could run either way: bad experiences may push people out, or people who leave may remember their childhood religion more harshly.
What do people often get wrong? One mistake is to think that questioning means leaving. Many people question and stay. Among Christians, 97% believe in God but 73% hold that belief with absolute certainty, so about a quarter believe with less than full certainty. Another mistake is to think that people who leave religion stop believing in anything. In Pew’s 2024 report on the religiously unaffiliated, often called the “nones,” only 29% rejected the idea of any higher power, and about half said spirituality is very important to them or that they think of themselves as spiritual.
Many sacred texts include people who question:
Traditions also set limits, and it is fair to say so. The Catechism of the Catholic Church lists voluntary doubt, a refusal to hold as true what God has revealed and the Church teaches, among the ways of sinning against faith. It describes involuntary doubt as “hesitation in believing” or difficulty with objections, and warns that doubt deliberately cultivated can lead to spiritual blindness. The Catholic question-and-answer site Catholic Answers explains that involuntary doubt is not sinful in itself and can be felt by any sincere believer.
Questioning can hurt. In a 1999 study of a national sample of Presbyterians, religious doubt was linked with more distress and lower well-being, especially in younger people. Not every study agrees: some have found no clear link between doubt and distress. A 2009 study that followed U.S. adults aged 66 and older over several years found that people who had more negative run-ins with fellow church members had more doubts, and were more likely to push their doubts down. Pushing doubts down was linked with worse health. In another study of older Christians, support from a pastor softened the link between rising doubt and depression, though only for men. These studies show links, not causes, and most looked at older Christians in the U.S.
One practical lesson: you do not have to carry questions alone or keep them hidden. Here are some ideas for talking with family.
Families with different beliefs are common. In the Religious Landscape Study, 26% of married U.S. adults had a spouse with a different religious identity, including 13% where one is Christian and the other has no religion. A trusted friend, a counselor, or a faith leader who welcomes questions can also help. If you feel hopeless or unsafe, please use the crisis line on this page.
Meaning rarely comes from one place. In Pew’s 2017 surveys on meaning, 69% of Americans named family when asked what makes life meaningful, while 20% mentioned faith or spirituality. Friends, work, time outdoors, pets and music came up often too. For many people who stay in a faith, it remains a main source of meaning: 56% of those who kept their childhood religion say a key reason they stayed is that it gives their life meaning. People without religion draw on many of the same sources. Atheists in Pew’s survey were more likely than Christians to mention hobbies and activities, including travel, and money. And 78% of nones say that believing they can be moral without religion is an important reason they are not religious. Our story Can You Be Good Without God? looks at that question from both sides, and What Does Science Say About Happiness? looks at why close relationships matter.
A small 2019 study, run at a Catholic university in Poland, surveyed 180 Catholics, with an average age of 24, who had recently been through a hard time. It found that the better people were at making meaning out of their religious doubts, the more satisfied with life they were. The authors say it fits the idea that questioning can be part of a healthy process. It is one small study that measured people once, so treat it as a clue, not a rule.
The answer stays the same. Yes, it is okay to question what you were raised to believe. Where your questions lead is a personal choice that science cannot make for you.
