Believing the Earth and the cosmos had a beginning is a direct result of witnessing the 'beginning' of life (and other things) during the lifetime of a moderately thinking human. Ancient peoples would observe the beginning of such things as life (and storms) and extrapolate it to their entire environment. There is nothing special about the idea that the Bible suggested a beginning to the cosmos, in fact it is a common thread through many early human belief systems.
Unless you are suggesting that the Bible talks about the BB specifically. (You will need to have a good grasp of what the BB is and its consequences before making this claim)
" Trying to disprove Creation will ultimately prove it.
Science does not try to disprove the creation stories. There is absolutely no intent to do so. The disproof of the Biblical Genesis stories is a logical result of trying to investigate the natural world. The disproof of the Biblical Genesis stories do not in any way disprove the existence of God.
You seriously don't think that the origin of life has nothing to do with Evolution?
