Do you believe or maybe have some clues that advanced Alien beings exist and that they interfered to the advancement of Humanity in historical times in secret ways or even today they watching us or helping.
I rather think if they exist and if they traveled a long distance to the planet Earth to visit Humanity that they are secret watchers or helpers if they are so advanced than what is the point to want to destroy other civilizations like humans. I mean we are like babies if we want to compare with their technology or body and brain biological advanced anatomy of them.

Some conspiracy theories are so mad that they think that there are evil alien civilizations that secretly enslaving humanity and want to destroy us. Man think about this if there are some smarter and more developed than us then they must overcome issues with negative emotions and killer instinct.

They must have brains and heads much more in weight than humans because if they think and must be enormously creative to advance in the technology field, and to solve other social orders and organizational problems very big minds are needed.

I think that there are historical pieces of evidence and even today occasionally they reveal their presence in secret and small portions.
