The denier (of ET) mindset is an interesting one. Above all the denier values scientific data. In the absence of scientific data to ET deniers simply reject the notion as someone's imagination. Unless data is reproducible on a machine, to the denier, it doesn't exist.
Imagine gravity for a moment...does it exist? Or rather, did it exist before the 1600's when it was "discovered"? Of course! Gravity didn't suddenly become imagined by Newton and ground humans who up until then flew from place to place, nor did the gravimeter create gravity. Deniers want an ET-meter before they accept that something more exists to the universe. There are those who see the apple falling and know gravity is causing it, then there are those who refused to believe in gravity until a scientist (technically mathematician) describes and measures it.
Proof that aliens, or the afterlife exists:

You can't explain this with science (yet).
