What is the meaning of the latest doctor who series ending series 6 2011?

well it takes a lot of explaing and one heck of a lot of guesswork but here goes...

As we found out, River Song is Amy and Rory's daughter, melody. Melody pond was her name but it was changed to River song because in the language of the gamma forests there is no Word for 'pond' because the only water in the forest was the river so pond changes to river. Melody is a song so Melody changes to song. Put the two Words together and switch them around it says 'River song!. There was also a debate on whether River was even human.. This was because the doctor scanned her DNA and it read human plus time lord. The explanation for this is not that the Doctor had the baby with Amy but because the baby was conceived (by Amy and Rory) in the TARDIS while it was in flight. As we know the TARDIS travelles through the time vortex and the Time lords became what they became through prolonged exposure to the time vortex which basically means they travelled in time a lot. So following that information the baby must have absorbed a bit of the time vortex while it was being conceived. So if the baby-River Song is part time lord then she may be able to regenerate. Following that theory, i think river may be the little girl we say regenerating at the end of 'Day of the Moon'. If that is true, River was the girl in the Spacesuit who killed the doctor but when they travelled back in time Amy shot the little girl to save the doctor therefore killing her own Daughter! River also said 'this girl obviously forced herself out of the suit, she must have been incredibly strong.' If this girl was river and a time lord, that could explain her incredible strenght(not that i know time lords are incredibly strong). So the episode ended in a HUGE cliffhanger but revealed after three years of Mystery who river was. One thing i dont understand is why River would kill the doctor. Maybe the doctor does something within the 200 years that separate today with the doctor's death that would anger River. I must now inforce that this is a GUESS and I DO NOT KNOW what is true and what is false but I cannot make a better explanation from the information I already have. But if ther is one thing I have learned from watching Doctor Who over the years is that You can NEVER know for sure and that NOTHING IS EVER AS IT SEEMS!
