In the Genesis there is the "God created the Universe in six days" thing.

Clearly this text was written before the individual who first wrote and BELIEVED this could not possibly had a solid understanding of the concept of a "day". A "day" on Triton, for example, comes and goes seemingly predictable, and if you consider a celestial system described as the "three-body problem" the pattern is truly unpredictable.

So, do I believe in the Genesis? No, I do not believe God created the Universe in 6 days. The best I do is to believe that God indeed created the Universe.

I leave it up to God to decide regarding the consequences for my denial.
