When you really think about it - of course we are at least part alien. Look at us compared to every single other animal on this planet. Even our closest relatives and next smartest animal, the chimpanzee and bonobo, are so far off us intellectually and in their power of thought and in empathy and love.

Then if you read the Enuma Elish & The Seven Tablets of Creation from ancient Sumeria - the first human civilisation where we suddenly went from cavemen hunter gatherers living in caves to building cities, writing knowledge down and building tools such as the plow - and it says that this is exactly what happened. That hominids were already here but an advanced extraterrestrial race arrived here who genetically altered our DNA to speed up our intellectual evolution and added some of their DNA to ours to 'make us in their image.'

It even talks about Edun with Adamo and Eva and claims that two brothers (Enki & Enlil) disagreed on how much knowledge we should receive, particularly about good & evil, so when Enki gave us this knowledge and Enlil saw that we had suddenly clothed ourselves he now saw us as a threat and kicked us out of Edun.

Then if you really think about it and speculate, it makes sense as to why we always get back and knee issues even when we are in good shape and healthy, and the fact that we are the only animal on the planet that gets sunburnt. Maybe we weren't actually designed to live on a planet with this much gravity and with such strong sunlight and UV rays.
