It also speaks of how you should beat a servant if you think he has done wrong.

and it also tells you about healing a leper with a dead birds blood....

and the bible also speaks about two different stories for Jesus' birth which can be proven wrong.

The bible talks about how you can heal a skin disease with a dead birds blood...

your an idiot...

we have a common ancestor the same as dogs with wolves.

the point is not that we say 'God couldn't have existed forever' but that you use the universe requiring some creation because it is complex or something and then you claim something more complex (God) can exist forever which is then a contradiction.

Also for the big bang, we are slowly getting close, we have even identified what happened in the mere seconds after the big bang (gluons turning into protons etc).

although it is possible that the universe has existed forever as a big bounce (universe expands then contracts really small the explodes again).

If your on about the start of life, well we are getting closer; I am sure you have heard of the Yuri Miller experiment which created amino acids (required for life).
