Some say that we evolved from apes. Well, if this can be proved as fact, then how come modern apes don't evolve at all? Some speculate that Extraterrestrials may have some how edited their own DNA in a form of cloning to continue their race in the form of humans. Then there is God. God, in my personal opinion, may have created us in a way that we can't understand. For example, God could have possibly given us message, split it up into millions upon millions of puzzle pieces, and scattered them across a table that we can call Science. We just have to put the pieces together, and we'll find out that what we believe to be true, what we read about in our Science books and Encyclopedias, may be false because the puzzle pieces are in the wrong spot.
