Do scientists believe in Gods

Christian, Muslim, Hindu...etc? I always wanted to know? Mostly talking about cosmologist?

Most scientists don't and it differs from field to field. There are more biologists who believe in God than there are physicists and I think a lot of cosmologists are atheists, but there are some that believe in God. If I remember the statistics correctly, about 40% of biologists believe in God or gods and about 20 - 30% of physicists believe in God.

A scientists need to not be prejudiced by their beliefs but are otherwise free to believe in gods, they just need not taint their efforts by forcing religious resolutions. However, many good ideas started with religions, universities were the creation of religions which is why you wear a cap and gown at graduation. The Big Bang Theory was a Belgium Catholic Priest asking the question what if everything had a single beginning? But science itself should not be cherry picking to reinforce religion as creationist's do, asking science to outright prove your religion is simply lying. If you bias your research, you're doing both science and your religion a disservice. To a certain extent, science was born out of religions and that's fine but bending science to your presumptions from religion is just wrong.

YES some scientists do believe in a god.There is a big difference between believing in something and knowing the facts about something.Scientist that believe in a god do so because it is only a belief which is perfectly acceptable in science as long as it does not provoke the facts of science.

Some do, some don't.
Although, nowadays at least, most scientists tend to be atheists/agnostics.
It's irrelevant though, so I don't understand why you're asking the question. Religion & Science are two totally different things; even Pope Benedict the 16th concurs.

Some of them do, some or them don't.

I do. God IS physics. :"...May the F = m x a be with you...".
