Can quantum theory explain why extraterrestrial life must exist?

[vin300]

This is not a serious post; I was wondering why there must be so much speculation over extraterrestrials exist or not, while they had proposed with the quantum theory on the "existence of the scrutinized" so everything MUST be seen at all times, which is only possible if life exists alongside matter, and ubiquitous.

QM does not say that everything must be seen.

Even if it did, why would aliens be necessary? I see you. You see me.
If one of us is on an alien planet that changes nothing.

Because in the uncharted sea of space there must be dragons.
