This theory depends on Contradictions in human history; especially inconsistencies between the fossils and the creation. The inability of evolution and the creation to respond to all questions. This situation has brought a different theory to the agenda in the last period:
Giant and real human lived in the past.
There is some men fossiles are bigger and bigger than the man in present day.
One of them:
The other one:
There is another:
And others:
This fact shows that history is different and that gigantic people lived. But religious and empirical history does not mention this as history of human. This proves that something from the human being wants to be concealed.
The strongest theory on this subject, Giant people were real people. They left this world For a reason. According to the theory of neighboring worlds, they settled in one of the worlds on the other side of the antarctic. While leaving our world, they wanted to leave to this world the "caliphs" that were genetically similar to themselves, representing themselves behind. For this reason, todays human beings are produced by genetic mutation of real human and phsically from animals in the world. According to this theory, our world has begun at a primitive level while the last level they reached.
In that case, before the first man thought about wearing clothes yet, those giant people were the ones who would do genetic researches.
In this case they are very advanced in technology right now.
But why they are not interested in our world at all, or if they are interested, how they do it without noticing it. And the big question is why they have left our world.
