OK, that last sentence tells me all I need to know about how little you actually understand science.
Let's talk about GEOLOGY for a second. What "experiments" do you think geologists run to know, say, what the Mantle is made up of? Do you think that they create a completely new planet earth and see what happens?
What "experiments" are run to learn the history of the earth?
Do you not believe that geology is a science?
Wrong-o. But you believe what you want. If you actually CARE about learning the history of the AGW concept you can read about it here:
Global Warming Timeline
Well, you are pretty much wrong all around, but that's because you seem to be ignorant of just about everything involved in this concept.
You can always learn. (One assumes)
