I'm in the gray about it too. I have had many subjective experiences regarding 'them', and I've also seen a 'nuts & bolts' UFO with my husband, when we were just going out. So my opinion is, that there is 'something' out there, but we tend to project our beliefs to the experiences, when they're 'first hand'. I don't know what this means, but I essentially don't believe anything anyone says about them. Heck, I don't know what I believe about them. I just try to not believe anything, because belief is for mythology and religion.
