People often say, be open minded but not to a point where your brain falls of. One of the greatest mysteries of todays world is when and how did humans first appear on planet earth. To date I have heard or read of 3 major theories. These include 1) We were placed on earth by God and the first two humans were Adam and Eve. This is the view of all people following an Abrahamic faith(Judaism, Christianity and Islam) People are often considered non believers and ostracized from the community if they possess a view different from that of scripture. I think this is a load of krap. People are entitled to ask questions. It is only the clergy who dont have the answers or too ignorant to find out for themselves who make such a pronouncement.
2) We evolved from monkeys or apes via a process of natural selection set out in Darwins theory of evolution. This the view of many atheists and hardline scientists. Sometimes when you see how people behave, you would definately think we came from the apes. or 3) We were placed on this earth by aliens or that our ancient ancestors possessed superior sets of technology that flew us to earth from another planet. This is a view that would have been laughed at a few years ago but if one does a simple Google search, one would observe many websites dedicated to investigating such a belief or of persons who support such a view. One of the main sources of this belief include, the discovery of the Sumerian Tablets(Sumeria was a prehistorical advanced civilization) in Iraq which indicates that an alien race known as the Annunaki arrived on earth from the planet Nibiru and genetically modified organisms existing on earth into humans (known as the Adamu (Could this be Adam)??) to mine gold for them. Gold was allegedly needed by them to keep there atmosphere habitable. Other evidence to support this view include the Nazcar Lines in South America (You cannot see these standing but only from the air - Why go out of your way to create this when you not going to be able to see its effect for your self), our natural reaction to looking up in the sky when praying to God, other megaliths(Pyramids of Giza, Macchu Picchu in Peru and Baalbec in Lebanon) which were built using engineering techniques that baffle even the best engineers and architects to date.
Despite all of the above, nobody can prove to you exactly how we got here. The only thing we can do for the time being, is maybe wait and see what we human beings evolve into, this doesnt seem to be happening, wait until another spacecraft from Nibiru lands on earth (that's if they still there or if they ever existed in the first place) or wait till death to see what is on the other side.
