The Insignificantness of the Ocean

I've been watching Shark Week ever since I was a kid, so it's been going off for a very long time. The crazy part to me about the ocean is that we've only explored maybe 10, 15... Isn't that wild? It made me feel so insignificant on this planet. Cruises are nice. They are fun. But that is one part that I did not like. When you go outside, you literally cannot see anything. Especially at nighttime. That's what it's really scary.
