I like finding pictures in the clouds. But I don't for one moment consider them to be real.

Aliens? Probably! If evolution has occurred on Earth, no doubt it will have happened elsewhere too. It is however most unlikely such beings would be anything like us.

The Supernatural? If at all, only because we have yet to find a NATURAL explanation.

The problem with proof and belief is really about superstition.. Science has progressively disproved many 'no-proof' ancient beliefs eroding away the volume of superstition still remaining to believe without proof.. I have 'irrational' beliefs too..

Hi -- I'm new here, but I'm afraid I'm exactly what you're talking about. I want evidence. I know we don't know everything and may never know, but that doesn't mean I'm willing to break the laws of physics that we DO understand. As for aliens, that depends on how you define it. Do other life forms exist somewhere? I think it's likely, based on the sheer size of the universe and the fact that we're not in the center of it. But do I think little green men visited New Mexico in the 50s? Nope.

Have you read Carl Sagan's "Demon-Haunted World"? If not I highly recommend it.

I am open to the possibility of alternate universes, not necessarily anything like ours, but composed of anti matter and anti energy, part of my mind thinks that where they touch is what we call black holes.

Since 95% of the universe consists of black matter and black energy which is invisible and unknown to us, I'm pretty confident that the 5% we are aware of is a tiny part of the whole picture of what is possible to know through current "facts" and "proofs". I like to say that we are like blind people examining the tail of an elephant attempting to speculate what the rest of of the elephant looks like.

My personal opinion: If there is no evidence, facts or data for something's existence, then that something does not exist.

You can't say something that is untestable exists or doesn't. On these matters people will always differ on opinion and until there are tests that can be done, repeated and predictions proven that's how it will remain. On the subject of aliens, I struggle to believe in humanoid aliens (however I cannot deny their existence) it would suggest common ancestry, and I've not seen evidence to suggest we've been visited. There is how ever a very good chance of life out there, the universe is massive. There are little animals known as water bears (tardigrades) these animals are so Hardy they can survive the vacuum of space and even live without water for years. These creatures give hope to astrobiologists of finding life in the universe, it could be silicone based instead of carbon who knows, but the theory suggests its going to be so different to life as we know it we might look straight past it. I hope to see it in my life time!

Sadly, I admit to a fervent irrational belief...that one day I will win the lottery! On the flipside, I just convince myself it's a poor man's tax for a couple of moments of dreaming.

You can't expect proof, although disproof is possible. That which is not disproved remains possible, however unlikely it may be.

no, occam's razor, logic, and rational thinking applies equally to gods, aliens, and the supernatural, of course.

I think nothing needs to be taken off the table. Some things are further toward the edge of the table, but that is subjective to the person. Aliens, supernatural (though, if it exists within nature, then it is natural, isn't it), cryptozoology, etc. are all interesting and the idea/possibility make life more rich. When I was in high school, we had a great debate on multiple dimensions of existence that started as a discussion on Yeti/Bigfoot.

Got to admit Chariots of the Gods, in the movie theatre, was convincing for awhile.
