Of course assumptions aren't evidence.
Drake, Shostak, Grinspoon, Sagan...
And I'd have to say that the most significant assumption would be that what happened here on earth is nothing unique in the cosmos. The copernican principle.
Others might be that there is a prebiotic chemistry at work in the cosmos seemingly geared to produce Life, that microbial life may well exist in our solar system, that earth like planets around sunlike stars (but by no means precluding other types conducive to Life) are abundant, and so on.
