We’ve been going to space and landed on the moon a couple times I think, since the sixties but we are barely able to explore the deepest part of the ocean. What’s this about?

It is not easier.
People visited the deepest part of the ocean before anyone went to space.
Sending people to the bottom of the ocean is both easier and cheaper than sending them to space.
However, there is not much a person can do inside a submersible that an unmanned submersible couldn’t do – for much longer and even cheaper yet.
The possibility of a human doing a “spacewalk” at the bottom of the ocean is near zero. The pressure at the bottom of the ocean is about 16,000 pounds per square inch. That is over 3,000 times the pressure inside a spacesuit during a spacewalk. Engineering a pressure suit for walking on the bottom of the ocean is very, very far beyond our current technological abilities.
