No. Personally, I'm an agnostic atheist/secular humanist for a multitude of reasons, some of them being as the result of getting a better understanding over time of biology, geology, genetics, astronomy, philosophy and mythologies. Over the years my stance has crystallized to what it is now. I could be wrong of course, but I'm an avid seeker of truth and this is my understanding of it and where I am so far.
As a kid I found the Ancient Aliens idea to be very cool, but I find it really weak nowadays. It mostly comes out of either not understanding how evolution works or by believing are ancestors were too stupid to do the things they did. And we have good counter-evince for all the basis of the Ancient Aliens hypothesis. It's not impossible, but I really doubt it happened. The simulation hypothesis is much, much stronger IMO.
I think that life somewhere else in the universe is completely possible and even probable. Intelligent life is also possible IMO but I'm not at all sure how probable it is. There are some great discussions about the Fermi paradox.
That's why I was disappointed that Scott went with Ancient Aliens, it was unnecessary to have the Jockeys create us. I love when the film franchise is as realistic as possible. The FTL, artificial gravity and especially the super fast growing alien without eating is more than enough fiction in this Sci Fi, so I'm glad whenever other hard sci fi elements are enforced.
