Was there gravity at the start of the universe? If so, how do we know? Was there gravity in the early days of Egypt, as we know it? The evidence seems to suggest that it is a bit of a mystery how they moved all those now heavy blocks.
From a biblical perspective, I see no reason to assume gravity existed as we now know it. (Of course there were laws in place to keep us from flying off the planet, etc, but whether identical to present gravity, I do not think we can know by science)
From a science perspective, I don't think there is any proof there was either!
Guess it it merely an matter of opinion then?
