If God is almighty and not bound by time; I see no reason, why the story about the creation of the universe, as told in Genesis of the christian Bible, and the scientific story about the appearing of earth, life and man should not both be literally true.
Assuming the biblical genese and the scientific genese both to be true literally; I can only speculate about the why and how of the emerging of the scientific truth. Maybe the scientific truth is also created by God in relation to human sin or maybe it is created by the wishes, beliefs and expectancies of humans. Whatever. Maybe the disbelief in the biblical truth removes that truth even further. The biblical truth asks believing; confirmation might come later. By seeking confirmation first, one might cause or find non-biblical confirmation.After all, the scientific story can hardly be seen as a story more in favour of man. The earth is a tiny spot in a gigantic universe, the durance of human existence is one moment in an enormous sea of time. Apes are our ancestors and our origin lies somewhere between a big bang and coincidence.
