Yes, the Earth is not moving, which is why it's possible to jump from, and land on, the same spot.
That's because the train is moving and your body is moving at the same speed,
while it's standing.
But how high can you jump? Let's say one foot before landing within two seconds. It's only two seconds, so your body would obviously still be moving at the same speed as the train's while in the air, enabling it to land on the starting point.
When you were inside the moving train preparing to jump, your body was standing on a solid object that was, at the same time, pressing against the Earth, enabling you to move at the same speed as the train's, before jumping and staying airborne for only two seconds.
As for aeroplanes:
1. The atmosphere that aeroplanes fly in is obviously not solid,
2. The time that aeroplanes spend in the atmosphere is certainly well over two seconds, not to mention aeroplanes can
change their flying speeds while in the air,
3. And aeroplanes do not take off vertically, nor do they jump.
So the physics for aeroplanes is different, right?
Were you hoping to land on the same spot?

Well, obviously, I disagree because that video alone
truly proves that the Earth is
really not moving.
Yes, that would be correct
IF the Earth is a perfect sphere, spinning at roughly 1,000 miles per hour and taking 24 hours to complete one revolution, resulting in a circumference of roughly 24,000 miles and a diameter of nearly 8,000 miles.
Just like what PretenderSam said:
the flat Earth
can and
must have a diameter
if it is also circular.
And obviously, I would say that the Earth is definitely flat, stationary
and circular, therefore it has a diameter.
