We are not from this planet, possibly from Mars&Nibiru???
Well, here is the proof:

main reasons why is that are

I - This planet has more intense gravity then our original
II - This planet has too fast circadian rhytm then our original
III - This planet is just too close to Sun then our original
IIII - Sun radiation is far too strong for us to survive

I First and main proof is bone breaking, if we are made for this planet there is no way we could break a bone when we fall on ice or snow, we should be able too jump higher, and not to hurt ankle. All sort od injuries we have just because gravity is too strong on this planet. There is nothing bad in feeling heavy, it is for the gravity too strong. Yes, also bone diseases and pain, spinal pain, discus hernia, that shouldn't happen if gravity is smaller.

II I bet all of you has this problem from time to time, just having to have one more hour a day, and everything would be just fine, I am sure Earth has been manipulated somehow to prolong duration of day, but it was impossible to make it longer, because all plants and animals here would suffer.

III If we look directly at the Sun we can damage eyes, that is not logical if we were adapted to this planet. Also UV rays making more damage to our eye system, in fact we all feel just right when sun is lower and during cloudy days, no kidding, all northern countries are more industrial developed. it is because of that reason, heat is good for reptilians only. (there was one movie with Charlie Sheen about that
)

IV If there wasn't strong XXstrong magnetic field Sun radiation would kill us, that couldn't happen if planet is on greater distance from Sun..

There is plenty of proof, reasons why is not logical that we live on this planet, more correct we are not from here, or partially our genes are not.
