And consider this, if Adam and Eve were superior to current mankind in both intellect and physical form, obeying their own rationality and relying on their own abilities would be far more tempting that it seems to be in hindsight.
People who argue that the Universe is too large for there to be only mankind have a very, very, limited view of both what God originally intended for His creation and of the Creator, too, if they believe in God at all.

I believe there universe is so large because His original intention was for us to do exactly what he said to do, “be fruitful and multiply”, on a far grander scale than what we’re limited to on a single planet. I also believe that’s the final reward God has for those trust and obey Him; man restored to being capable of doing what God originally intended before man chose to obey himself rather than God.

A quite similar thought has crossed my mind a few times too.
No idea how accurate it is, but whatever the good Lord has in mind I bet it’ll be far better than anything we’ve imagined.
