Further back in the thread BD, Tower of Babel.
The tower of Babel
5 But the Lord came down to see the city and the tower the people were building. 6 The Lord said, ‘If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them.
So, literally anything? Stuff like being able to exist and not exist at the same time? Grow an extra head? Believe in God and be an atheist? Go back in time?
Is there not an unwritten assumption that the Lord here is speaking about stuff that humans are potentially able to do, but which they so often don't?
