The angels didn't specify stratus, cirrus, or cumulus clouds either ... so what? ... the angel said He will return in the same way.
He left from the earth, He will return to the earth.
He left from the Mount of Olives, He will return to the Mount of Olives.
He departed to heaven, He will return from heaven.
He was seen leaving, He will be seen coming again.
It's really very simple.
I perceive there is nothing left to debate with you.
Philip
