The earth is not a sphere due to the Horizon-Line

The Horizon of a sphere is explained that it is the ground that begins to slope-downwards until you can't see no more.

The Horizon-line could never be seen with an upright eye-level, but always looking down because on a sphere the horizon is the ground that begins to slope-downwards until you can't see it no more.

But that is not what we see.

The Horizon-line would never be seen at the middle of any photo but always at the bottom if the earth was round.

I realize that this new information is extremely shocking and will leave many in quiet dismay. Please do not panic, the authorities still care about your well-being.

I hope that this truth will not be deleted.

Seeing is believing...
