why do people have to be "taught" to dig a hole in the ground?

@davetileguy

Digging a hole in the ground looks easy, but it isn't. Digging a 2 foot hole is easy, but digging down to the groundwater is a big challenge. How do you lift the drill bit when it weighs a hundred pounds? How do you clear away the dirt at 100FT? How do you drill through a sandy layer when it keeps collapsing when you remove the drill? How do you drill through rocks? Etc etc. Hope that answers your question.

@1framistan Wow! all incredible technical challenges !Duh lift the bit with a winch,hand powered or gas /electric ,cable tool to lift the dirt or mud pump, clay or casing to stop wall collapse, You must be joking ,you think mining is any easier? I think the Chinese figured out how to drill a few thousand years ago. It's a HOLE,don't try to make it anymore complicated than it is.
