What do aliens look like? If you believe they exist, you’ve probably wondered what they might actually look like. Hollywood has commonly portrayed their appearance as little grey or green men with big eyes and a big head, or large monster-looking beings equipped to destroy the human race. However, what do you think they really look like? Of course, this is a question scientists are diligently working on and nobody can answer at this time. Regardless, for now we can only speculate what simple as well as advanced life might be like. One thing is certain, we must keep an open mind. There are still many facts about the cosmos we know, but many more we still don’t know. However, we are definitely aware of its incredible size.
