1) It is fact, not imagination. Bigger brains means more synapes and nerves to do complex processing. That's what differiantiate man to animals. Smarter animals comes with decently sized brains (like dolphins etc), while dumb animals comes with lesser brains. It's like your CPU. A 100 million transistor CPU is definitely more powerful than your 1 million transistor CPU.
2) You are wrong. If you google for aliens or ancient aliens or ancient UFO, you'll find many photos of evidence in forms of paintings and and other inscriptions in tombs and such depicting many UFO-like and Alien like creatures. Back in those days, people don't know what it was and simply assume them as gods/demons/angels and some other supernatural stuff. They also don't have the internet, thus it is impossible for them to share and discuss this phenomena and coins a popular term out of it.
1) I would give you. However this doesn't really mean bigger brains are smarter. There are kids who suffer some sort of weird disease and have a very big head. Are they smarter? Nah. The only thing that makes human smarter is that the brain can have quick synapses, which means other parts of the cell of the brain can quickly communicate to each other.
2)However, there is one thing that really intrigued me during the Aztec's conquest by Cortez. These Aztecs drawings and description about their God Quetzalcoatl looks exactly like Cortez, the spanish conquerer. Descriptions include "A god, wearing long Hat, come by the sea, holding with him a
new weapon".
Cortez, were wearing spanish hat, came by the sea and also bringing with him is a rifle. So your second point reminds me of this. Were those ancient Aztecs saw even before Cortez came?
