There are roughly 100 billion galaxies out there. And each one has roughly -- on average -- 100 billion stars. And each one of those stars can have dozens or even hundreds of planets.
We have only looked at maybe one trillionth of one percent of what's out there. We are just finding water on planets and moons that are right next door to us.
Your premise is absurd.

I probably shouldn't have separated these two sentences from the preceding paragraph. The subject was trees of life that have been found on earth. There is evidence for only one. Sorry for your confusion.
Now, as to the absurdity of saying that life has arisen only once in a Universe of a hundred billion galaxies (that's just the observable Universe, by the way), until extraterrestrial life is actually found it's presumptive to call that hypothesis ridiculous. We can guess, but we don't know, how prevalent life may be.
We may be the only instance of intelligent life. I think microbial life has probably arisen wherever conditions are favorable, but that intelligent life may be exceedingly rare.
