A religion that isn't based on truth isn't worth anything. I see nothing wrong with the belief that God created. And it is impossible for scientists to determine how or when God created. There are CLEARLY assumptions being made based on what is expected of natural processes; however, no one has determined that nature came about on its own. So, the proof of anything is relative to what one is willing to assume and accept.
Scientists can't determine something that never happened. It is you that is making the assumption that there was a "creation event". There is no evidence that the universe was "created". The laws of physics state that the universe must always have existed and will always exist in some form or another.
If the current laws of physics prove to be inaccurate we can always change them to fit reality. It's the great thing about science. You can swear it's the truth one day and calmly say you were wrong the next day. No harm no foul.
In short--Science need sceptics, religion need believers!
