to harbor extra terrestrial life

Saturn's moon Enceladus is one of the more likely places for extraterrestrial life in the solar system. It has liquid water around geysers which may harbor life.
Ganymede and Europa have ice-sheets which may contain water liquid water farther down, which could harbor life.
Saturn's moon Titan has an appreciable atmosphere which could contribute to life.
Most scientists have recently given up on Mars.

I rather like the "Pan Spermia Theory".
That a form of life has been travelling around the universe for a very long time. When conditions are favourable this form will evolve into appropiate forms for the available conditions.
There are two discoveries that in my mind lean towards this idea.
Anarobic bacteria that were discovered deep in the earth's crust. they don't need oxygen sun etc just minerals. They could be anywhere on any inhospitable planet (well, there would be limits). Aparently similiar bacteria found in a meteorite that had originated on Mars.
The inference I am making here is that all life may have evolved from these bacteria, that they arrived on earth as it was forming and as conditions suited they evolved into us.
On Mars this may not have occured and maybe they are still there as they are here but with no terrestial style descendants.
i draw your attention to the fact that recent experiments and plans to experiment involve deep penetrations of Mars and that comet etc. I suspect one of the agendas is to see if something like the anarobic bacteria is present.
If the panspermia theory is true then any other life would be related to us.

Well scientists think that Mars used to harbour small microscopic organisms but I guess that the best answer is in the moons of Saturn. They have found water traces on that planet. Why don't you visit astrowhiz on Yahoo Groups..you could start a discussion on astronomy and ufology??

In ours, it's unlikly any remains.
It's possible there was some on Mars and we think the building blocks for life exist on Saturn's Moon Titan.
