Thats the argument i hear in more sensible Creationists. That 7 days is just a metaphor and since time is meningless to an omnipotent being that could mean millions of years of evolution.
Pfft. Creationism doesn't mean the Torah, the Tawrat, or the Old Testament. That is just Abrahamic religions trying once again to claim the sole authority over the concept of a god.
Creationism simply means the universe was planned and made into reality by some being, whether of it or outside of it is irrelevant, and whether it would visit the most infinitesimal part of it like a planet is irrelevant. If it weren't for Christians trying to steal an entirely plausible idea to mean what is written in their Bible, there would be very little controversy over it all. I just wish they would shut the hell up about it. Even if there was a Creator, it has very little chance of being the sky fairy in their cracked fairy tales mixed with history.
