Yes, religion is the game about lies, money, power and human control. But it is not about spirituality. Jesus was spiritual and he did not like the pharisee religion. Let me just say that the teachings from Jesus are meant so that we as human beings, if applied correctly can have an aesthetic appreciation for Life. Same thing for Hmong traditions. If you told me that a shaman can cure the person's cancer by doing some voodoo ritual and getting some dead ancestor's to help, you better take a hike.
The Old Testament is a gathering of deep thoughts by many different ethnicities from people around that region. The root of the Bible is in the first five book called the Pentateuch or The Book of Laws. These books described the history and origin of the Hebrew people and its lineage. These people are not white, they are middle eastern. The term middle eastern is vague because they didn't know the Far East 7,000 years ago. If I'm getting it correctly from the OP (original poster) I am aware what you mean by "white". European set out on the Crusade because they understood that the land there is filled with gold, silver, spices and goods. Just look at Egypt and all the vibrant history and gold. During the Roman times, they dealt in heavy trades with Egypt in Africa. The origin of Adam and Eve in the Garden of Eden is located in modern day Iraq. But it may have been sunken into the sea. This is proof because of how the Bible told EXACTLY where Eden was located by all these major rivers. So here are simple answers to answer your questions:
Origin of man is more then 7,000 years. Like I said the Bible only tells us the lineage of the Hebrew speaking people. They also spoke Aramaic and are familiar with vedic sanskrit.
The Flood and Noah. The Flood did happen but it was localized. Noah took all he could.
Abraham is the father of both Hebrew (Israelite) and Muslims. God's promise to Abraham to make his offsprings as much as the sand is True.
Is God a being and if so was he Jesus: God is not a being but a state of mind, a spiritual path. Jesus was a good example. For all we know, Jesus could be extra-terrestrial material, and the human species could of been from genetic material shot into space from somewhere far far away a long long time ago. I know humans would shoot human genetic material into space in case an asteroid could possibly kill us all.
It is a sad thing that all things grow will eventually die. Brace this idea and face it front on by being the best that you can be because this is your MOMENT! You didn't win the cash lottery but you did win the race to get to the egg race and fertilized the egg to be born. I say that's was a hell of a race, or divine intervention. Either way, you won! Hurray.
The Bible is the only book to lift your spirit. It wants to give you back your Life, your motivation to want to see a pretty perspective. If we all see the picture about Life, we can help one another out. We need nothing else besides GOD.
Did Jesus ever existed in human flesh? Yes, but he could of been a regular Joe who was intellectually trained and may have been a savant. Many other figures have been spoken of before also. Natural law is simple but could work in mysterious ways. Who knows!
