If I assert that there are no such thing as space aliens, it is on me to substantiate it.
No it's not, because as you said, you cannot provide proof of a negative. There is already the absense of obvious space aliens, and that's enough in itself to back up your statement. Unless, of course, space aliens show up tomorrow. It's up to those who say there ARE space aliens to provide some sort of proof, and that's where the burden of proof stays.
