Do you believe in Aliens or not!?!

My thoughts on the subject are .... that Aliens are Us from the future. This thought stems from the novel 'Sphere' by Michael Crichton, which I read about 20 years ago, and now with this recent video, it has me wondering if this theory of mine might be on the right course!?!

Supposedly, humans are going to develope larger eyes, smaller noises and bigger brains, and greater technologies ... so, it stands to reason that with the technological advances in 100,000 years ... it just may be that time travel might be possible ...

Anyhoo .... do you believe in Aliens and if so ... what are your thoughts!?!
