Why do theists think scientists are afraid to discover god at the source?

Answer is very simple with today's scientific knowledge. If the same question is posed 100 years before it would have been difficult to prove that the aethists are wrong. Just apply today's science for this question.Even in today's science we have so many umptions. Without faith in the unseen things, today's science is meaningless. In Mathematics, we say Limit tends to Infinity to solve so many real time problems. What is this Infinity? Human mind cant preceive this. Next in Physics, in Material Science, we ume a smallest wave particle called "Photon" which dont have any proof of existence physically, then only we proceed with atomic physics. Without such umption & faith, physics is meaningless. We measure distance in light years. Today the edge of our universe is 4 billion light years away from us. We cant even imagine 1 light year. So likewise we have so many things which we cant reason out. But we have to stop at some point with faith in it. Otherwise we will hit the wall and damage our head. Human mind is given with the 6th sense. We see, hear, feel, smell something but using the 6th sense we infer some results from such things. When we see a smoke at a distance we know there is fire. We believe this without seeing the fire. Like wise we have so many wonders around us, within our body which should make us to feel the presence of an omni-potent power. Within our science only we have so many faiths & beliefs, how can we prove God who is considered above all such things. We cant even imagine 1/1000th of a millimeter, but we cure the disease caused by a bacteria which is beyond our imagination. We cant even imagine 1 light year but we use our computers to calculate that the universe is 4 billion light years away from earth. This itself is a proof that the Almighty God exists above all these things.
