It is a widely believed fact that the ocean is deeper than scientists and the govnerment would like you to believe..
The primary reason the govnerment doesn't want you to know about what lies under the surface of the ocean is to keep the people from a mass panic. The creatures that live there are larger and more dangerous than any predator on land that we know of today.
Most modern day shipwrecks are actually due to monsters under the depths taking our resources in the form of ships. Many of these creatures consume metal to survive which is why our modern ships which are made of steel are at a far higher risk than the old wooden ships.
Scientists regularly flaunt the fact that the universe is infinite and has no end. Using that same logic it is easy to make the same assertation that the ocean is infintely deep. No human has seen the deepest point in the ocean.
This is fact.
Clear example of the ocean having no bottom is we have no photos of the bottom once the scientists leave the shoreline. The further you go from the shore the deeper it gets and it never ends. This is the truth.
