Yes, but the base is a distraction. People are so distracted by things like aliens that it has evolved into something greater when we shouldn't be so focused on it. Instead of letting people believe in these things, we should be encouraged to spread God's word. Show them what the Bible says and that God is creator. God would have to create the aliens for them to naturally exist. So aliens, bigfoot, reptilians, locness, all these different things would have to be created by God and yes he has the ability to do so but if they are created else wise its from the hand of Satan. Satan likes to duplicate God. He will drag people down anyway he can. So all the alternate worldviews and alternate religions stem from his deception. He's in the background laughing like " yeah I said there was a bigfoot and they believed it and now they're spending their time looking for it".
Personally I don't believe in these things and yes I think it's Satan's way of distracting us from the lord. Satan is a liar and will do whatever he can to keep us from God.
That's why I love the hymn "turn your eyes upon Jesus". It does not matter if they exist because I want God to have my time not Satan. "Turn your eyes upon Jesus, look full in his wonderful face, and the things of earth will grow strangely dim, in the light of his glory and grace".
