Sam2 said: If you assume that the 6 days of creation were 6 24-hour periods, there just isn’t enough time for any evolution.
Not that I believe there’s reason to think evolution happened at all, but Hashem could have sped up the process of change so that many years worth of species evolving and the world’s aging occurred in six days.
It has the same effect as saying that the six days took longer, without actually saying that they did.
