I'm remaining agnostic on all of them until, for example, some redneck pulls into town with a dead Bigfoot on the hood of his rig. I won't my breath - with as many people as have been beating the proverbial bushes for such things, I'd expect to have some strong evidence by now. I'm willing to be wrong on this.
With respect to extraterrestrial life - such that's visited earth, (excluding panspermia events), vanishingly close to zero. Other life, particularly microbial life, I believe the sheer numbers support the idea that there ought to be something, somewhere - but I'll still wait for something concrete before I "believe in it". I'm also willing to be wrong on this, but it would seem like such a waste of space.
