mp, nice trick. Before anything will begin to grow the next rain storm will have washed your experiment away. Life will grow, even on the side of sheer rock cliffs.
Perry, nice picture, clouds area a water canopy. It is a very real living cycle of the earth. Does anyone know how a evaporative cooler works?
And also explain how much water pressure would it take to turn a carbonbased life form and also how long under such pressure to turn it completely to stone? I am referring to the petrified trees in Arizona. To the best of my knowldege, trees have always grown on land. There is only one force of nature I can think of that would turn a living tree or a sea shell to stone. If anyone can figure the pressure involved and the depth of water it would take to do this, I would love to hear it.
Cofty. I have not answered your question because I fail to see how it relates to the OP. I will agree the Earth is very old, Millions even billions, I have no problem with that.
