I'm gonna have to stop you right there.
First of all, Christianity teaches that if you do not accept Jesus Christ as your Lord and Savior, you will be burning in a lake of fire for all eternity. This does not expressly use the phrase "inferior people" but be real, son. Christianity has a totalitarian worldview.
Second, the Bible endorses slavery in two ways. First, explicitly. The Bible says that it is perfectly okay to have slaves and you can even beat the shit out of them, as long as you don't kill them. If you kill them, you have to pay a FINE. I'm not joking. I can quote the verses for you if you like, or you can very easily look it up yourself. The second way the Bible endorses slavery is implicit in the Lord/worshiper dynamic. God is described as a king, not a democratically elected leader. You must worship him or you are an infidel. You must serve him or face his wrath. You must obey or be punished. This is a master/slave relationship.
We know how the planet works because we've examined it. We've observed and experimented with it. That's how science finds things out.
That's a great point to make about the corporate takeover of science (and everything else) but you are throwing the baby out with the bathwater. You're going to give up on all of science because of some corruption? What sponsor is making money off gravity? Magnetism? Or any of the other basic things science has discovered?1. Hydraulics. The hydraulics in your car run on... hydro. Water. Your engine doesn't run on it because it's not nearly as efficient or powerful as gasoline.
2. BIG WATER. Giant companies buy the entire freshwater supply of third-world countries and do what they will with them. If they could make an engine that would perform better than a traditional one, they would.
Energy cannot be free. Physics doesn't work that way, on the macroscopic level at least.
Darwin discovered the true origin of the human race. Tesla did not.
Tesla was robbed of his ideas by Thomas Edison. There was no conspiracy to destroy his work, as far as anyone outside the internet conspiracy world knows.
