Science is the process of observing, puting forth hypothesis based on observation and then doing your best to disprove that. It is the best method humankind has figured out for getting to truths about what we see around us. If you want absolute proofs, look no further than maths. In the real world, we do the best we can with science. Religion does not fulfill the same role as science do. Religion is not even close to the same concept as science. Religion is more akin to fictional works, like Tolkiens, lord of the rings.
