Like it or not, ideology plays a role in theories and what may be considered credible. Though today, modern discoveries are revolutionizing how scientists look at the universe and living creatures. Science is at its limit in some areas as it is realized that there are realities outside chemistry and physics.
The best answer so far is from Stephen Hawking, eminent theoretical physics professor and Director of Research at the Centre for Theoretical Cosmology, University of Cambridge. professor Hawking also held the chair held by Sir Isaac Newton and has written several books, his latest called the "Grand Design". In that book Dr. Hawking states that because there are laws such as gravity, the universe can and will create itself out of nothing.  This statement has several contradictions as pointed out by fellow Cambridge Professor John Lennox, which shows the degree in which scientists will go to discount the possibility of an intelligent designer of the universe.
For centuries scientists knew the universe was eternal, without beginning and without end and ridiculed the bible's narrative that the universe had a beginning. Then came modern science that discovered the universe indeed had a beginning, it was called the Big Bang Theory and it holds today. Scientists were very reluctant to accept this new discovery because of the biblical implications but never the less, the evidence made it impossible to ignore. So, now the discussion is what caused the Big Bang?
One such reality scientists are happy to consider is that there are enumerable unseen dimensions with enumerable universes of which ours is only one. This is one concept being considered to try and explain away the fine tuning of this universe for complex life. If there are an infinite number, then it is reasonable that one will be able to support life. There is no evidence for this concept but it is more palatable than an intelligent designer for many.
The only thing you have to do is ignore the data that points convincingly to a designer. Why would someone do that? Because their ideology doesn't allow for a designer. That is why Francis Crick said scientists must resist considering that the data points to design and remember that what they are looking at is evolved not designed.
Albert Einstein once said, "The most incomprehensible thing about the universe is that it is comprehensible." And although he was not religious, he was careful not to dismiss ideas in favor of scientism, or scientific dogma.
If you are pondering the big questions of life, like where did we come from, and why are we here, I encourage you to visit my youtube channel that is linked below. There you will find many Ph.D Scientists and Philosophers laying out the evidence for and against God. I guarantee that if these are questions you are interested in, the youtube site and the Blog, also linked below will give you a greater insight to science and faith.
There are some scientists who believe science can explain everything in the universe. Then there are many others who point out that all things cannot be reduced to chemistry and physics. Have a listen to professor of mathematics John Lennox of Cambridge University.
 
 
"I have repeatedly said that in my opinion the idea of a personal God is a childlike one. You may call me an agnostic, but I do not share the crusading spirit of the professional atheist whose fervor is mostly due to a painful act of liberation from the fetters of religious indoctrination received in youth. I prefer an attitude of humility corresponding to the weakness of our intellectual understanding of nature and of our own being."
