What are Aliens...?

Before we talk about aliens, let’s talk about how humans came to life. We all were apes, everyone knows this. Apes were short compared to humans and had a bigger brain and thus a bigger skull. Modern-day humans are taller compared to apes and we also have a smaller skull. This means we are getting taller as we are being evolved. Our brain is getting smaller too. That doesn’t mean we are turning dumber, but we are being more productive and efficient. Now let’s have a look at what aliens look like, or at least what people have reported about aliens. Aliens are tall and skinny. They got long faces with a small skull-to-body ratio. Didn’t we just see that humans are evolving and are slowly getting taller and the size of the skull is reducing? Yes, we did. Don’t you guys think time travel is soon going to be possible? Well, it is going to be possible and those creatures, known as aliens, are just the next era’s humans. They visited the past to give us information about their present but failed due to a lack of communication. It’s just a theory, I might be completely wrong. Let me know down in the comments what you guys think about this theory.
