No, I wouldn't say that..
The science operates in different way.
Yes, we have one "proof" and it is our own existence, but science also requires repeatability of experiment - and as long as we don't have another example (of extraterrestrial life form) in our hands, we simply can't say that life in universe is a rule rather than just a very rare (or even one off) exception.
Anything beyond that is speculation, whether we like it or not... All we have so far on extraterrestrial life existence is just circumstantial...
But just one other example, even in bacterial form (perhaps a plant or bacterial fossils on Mars surface) will make all the difference. It sounds like a bit formal approach, but that's how science works...
