If mankind can walk on the Moon (which we did 35 years ago), why can't we walk on the bottom of the oceans?

Maybe because they're way to deep?

It would be interesting to be able to see what lies at the bottom, but obviously it isn't a top priority. I mean, if they can put a man on the moon surely they can find a way for us to access something that is right here on earth. I don't have the answer though.

The waterpressure will crush just about anything. Someone has to invent something that can withstand all the water pressure. If you are a swimmer try swimmer down to the bottom of a 10 foot pool. When you get there you feel like something is hugging you. Tens that by miles and you get the picture.

I think its possible but we just need that invention. Get started. Just remember me when you get rich.

Well, we don't really need to. The engineering required to get to the sea bottom would be much more challenging than getting to the moon. I'm open minded about this and happy to be corrected but if you were to get to the sea floor in most cases, the pressure is immense, the visibility zero without lights and you'd get a limited return on your investment unless you'd found a wreck and wrer retrieveing the pre-nuclear steel or something. Most sea life is in the upper layers of the sea that receives solar radiation. Below that there isn't a huge amount, with the exception of the 'black smoker' colonies and the large mineral deposits that are just not commercially viable for exploitation yet. Also, most of the sea floor has been mapped using hyper accurate underwater surveys - thank you Cold War - along with radar mapping from space. It does beg the question though - more humans have been to the moon than to our sea floors!

Why is this thread opened up again? It's been since Feb since anyone posted and the OP hasn't been back since then. :(

Because the answers given were inadequate and lacking in detail. There was also no indication anywhere that the question was "closed." Is that OK with you?
