Nobody has ever seen the atoms, molecules and other fundamental particles like electron, proton, neutron, photon or quark etc? Not even by scientists with the help of most powerful microscopes. This is only our assumption that these exist. According to some scientists, probably we will never be able to see these infinitesimal fundamental particles in future also?
Scientists have only some evidences, information and a little glimpse about the existence of the atoms, molecules and other fundamental particles. Since billions of years from the beginning of universe these were in existence along with billions of galaxies and stars, but scientists have come to know about them only recently.
Even today we don't know their actual shapes, color, actual size and the material inside them. We have thousands of unanswerable questions about them. Scientists have failed to create even a single particle out of nothing. We don't know who created these particles? What was His aim? Who created the Mathematical laws, which govern the matter and non-matter throughout the universe? Is it not strange that all these particles are exactly alike throughout the vast universe?
It is stranger that nobody doubts on their existence and raise any question, but so many doubt on the existence of God. While no scientific theory can be explained fully, without acceptance of existence of God. None has ever proved that God does not exist, but billions have witnessed the existence of God in the past. Existence of prehistoric Scriptures is the greatest evidence of existence of God. The non-existence of proof of existence of anything is not a proof of its non-existence.
Most of the scientists believe in God, but they are not coming forward to accept openly the existence of God by the sciences.
Half the problem with society is that when you mention the word "God", they think of a man in the clouds with a white beard.
It is more difficult to perceive an intangible presence, existing in all things.
I also think that religious text can hinder understanding, as people take literal meanings, (which with careful consideration can have many meanings) and religious organistions tend to encourage literal belief.
Religion and science are not that far apart in some aspects of their search for the meaning and understanding of life - some people however will only trust one or the other.
I agree however that we should not get smug with what we know and what we have achieved, but examine closely the things which don't quite fit into our equations and take the bigger view.
