What do you think the Aliens are like on Europa and do you think Mars used to have a human like civilisation in the past or maybe Venus??

Europa: If there is life there some sorts of marine creatures. Saturn’s moon Enceladus might have a more hospitable subsurface ocean to life, though.

Mars: Possibly but probably unlikely

Venus: Very unlikely

@Bartleby Aquatic life appeared first on this planet. If another civilization viewed the earth from a huge distance they may see that the earth is about 3/4 covered with water and think the same thing about there being only some type of marine creatures here.
