We humans cannot understand the size of the universe. In fact, we have some idea, but it's just a perception. If we exist in this fabulous space, it's really possible that other types of entities exist too. Maybe not like here, on earth but, in some way extremely different and not perceived by our senses. There are some legends and constructions like the pyramids , that remind us about their possible visits in the past. Anyway, they could be close or somewhere this galaxy but, why shouldn't they exist?

We humans cannot understand the size of the universe. In *reality*, we have some idea, but it's just a perception. If we exist in this fabulous space, it's really possible that other *types* of entities exist, too. Maybe not like here *on* earth but in some *extremely different way* or *in a way that is incomprehensible to us*. There are some legends and things like *pyramids* that remind us about *possible* visits in the past. Anyway, they could be *near us* or *beyond* this galaxy, but why they couldn't *they* exist?
