LynchDate: 25 July 1983 21:19 EDT From: bruc@mit-ml One interesting speculation that I had about this -- if there is life on Mars, it's quite possible it came from Earth. Since material from Mars is believed to have traveled to the earth and landed in Antarctica (by being blasted from Mars by a meteor impact and eventually intersecting the earth's orbit), the reverse is also possible. I wonder if the spores of ancient microorganisms would be capable of surviving the voyage (suitably encased or shielded by rock).. Or perhaps life on Earth got started from a meteor from Mars or elsewhere. Maybe life in the universe only started once and then drifted to Earth and other planets. ...Keith
