Hey Sillyfellow- shut the fuck up. Nobody wants to hear your blather. Conspiracy nuts are irrational and will make up any excuse to believe what they want, no matter how unlikely. I have a friend who thinks McCartney is dead, Lennon is alive, the world is full of body doubles that somehow even fake out wives and parents, etc...
And most government conspiracies fall apart by the sheer logic of:
1. Most governments are barely capable of getting anything useful done
2. Most conspiracies are too complicated for those governments to pull off
3. Way too many people have to keep a secret, and there are frequently unintended witnesses to shoot holes in the story (9/11 anyone?)
Regarding Mars, the subject here- I assume this means 11m deep on average wherever there is water. Obviously some places are deeper, some more shallow. Earth is some 70% water, and it's very deep, so from a planetary perspective, I'd say Earth is "swamped."
