Nobody (publicly) knows. Yes, tablets incl. descriptions that earth (oxygen? pathogens?) was toxic to them and shortened their lifespans. The contagion of Gan of Edin was one of such breach that made them fall ill. Mostly they resided "in the sky" (assumtion: low earth orbiting vessels") from/to which they traveled in smaller landers (hence "the Tower of babel", which was not a tower, but a landing/lauching building for such landers).
Nobody has an idea why they left for sure. There are some claims, but I give them very little credit as there are no credible sources.
Many have claimed now for hundreds of years they are coming back "real soon now". Many dates have been given.All have come and gone, still non returning space ships.

Both good questions, imho.
