Could this be the real reason for global warming?

As I sit here reflecting on my 50-plus years of life, I have come to a conclusion. Global warming exists but not for the reasons the government has "fed" us to believe. And please tell me your thoughts on the matter I propose! I have learned in school that the core of the earth is that of molten lava..And several layers between that: one of those being crude oil. Yes oil! The stuff that allows us to have gasoline and lubricants among other things.    Now if you will humor me..imagine an egg still the shell...can you imagine the yolk in the center and the egg white all around it? And if you were to drill through the shell and take out all the egg white all you would have left is the yolk and an empty space where the egg whites used to be. When this happens the shell becomes weaker.  If you will transpose that scenario to the earth, yolk being the earths core and the crude oil as the egg whites.   Crude oil is a natural lubricant for the earth in the fact that oil protects the surface of the earth from getting overheated. For over one hundred years we have been sucking the lubricant,the protectant of the earth, away from the core. Oil that isn't there cannot do its job therefore the earth starts to heat up.   Personally I think we are way behind time in weaning ourselves off oil!
