I will debate your stupid logic with more stupid logic.Look at all the construction in the world today. We have put alot of buildings weighing tons on the land. Could this have a contributing factor, along with all the vehicles on the roads today? There is many things we, in the world today, have done that could contribute to this besides just drilling for oil.
The buildings, cars, roads, etc - all of these things were built from the land. Therefore, the earth weighs the same today as before the construction. We did not go to the moon or mars to get our building supplies
