Again... it's hard to appreciate how insanely difficult space travel is.
Just as an example, the lower stages of rockets are kind of like coke cans in terms of how much fuel they carry vs the actual machine itself. The engineering is insane. Just dropping a big chassis into the ocean in so much cheaper its hilarious.
Spaceships in many ways are safer than sitting at the bottom of a ditch with 7 miles of water sitting on top of you at 30,000 atmospheres of pressure.
It's also darker at the bottom of the ocean than in space.

Yes, space travel is insanely difficult.
But there is a reason why we still have not discovered the majority of the ocean. Because it is even more difficult.
