Biosphere Quote by Frank J. Tipler
“If the human species, or indeed any part of the biosphere, is to continue to survive, it must eventually leave the Earth and colonize space. For the simple fact of the matter is, the planet Earth is doomed... Let us follow many environmentalists and regard the Earth as Gaia, the mother of all life (which indeed she is). Gaia, like all mothers, is not immortal. She is going to die. But her line of descent might be immortal. . . . Gaia's children might never die out-provided they move into space. The Earth should be regarded as the womb of life-but one cannot remain in the womb forever.”

![“[Religious belief is] outmoded and ridiculous. [Belief in gods was a] worn out but once useful crutch in mankind's journey towards truth. We consider the time has come for that crutch to be abandoned. It is a vacuous answer... To say that 'God made the world' is simply a more or less sophisticated…” quote by P.W.
