Another paradox of going back in time that is not mentioned; is if say a person goes back in time, finds Ben Franklin as a young man and hands young Ben a copy of all his futrure witty sayings such as "A penny saved is a penny earned". Who is the author of those sayings? Not Ben and not the traveler.
Wait a minute, what if there is a "time" outside of time? Like you give Ben his own sayings, but you could not have gotten them without him having uttered them first, yet you go back in "time" to give them to him, but that is different from the foundational cosmological time-cloud in which Ben in fact was first regardless of time travel? Hash brownies are good.
ben frankilin invented dinosaurs.
Look sinner, you need to read Genesis 1 or 2 in the King James Bible in the language from the land you wish you were and take your pick which version is correct. Then you'll know who really invented dinosaurs and when (the order of creation is not important).
Personally I think Kevin screwed up.
