Someone once asked...
Someone answered with kindness...
The universe is a vast and ever expanding plane. The world will continue to create beautiful life and landscapes, many of which we will never know or experience. This fact may envoke fear in some, but you can find peace knowing life and nature encapulates all things. You can imagine the amazing unseen creatures that we have never experienced, and know they are living their own fascinating lives.

The earth has existed for far longer than humans have been on this planet. There is no up or down in space, it keeps going on endlessly in every direction. You're right majority of the ocean is unexplored. Look up to the sky, give thanks to the universe and stay blessed dear unknown reader!
