No one will agree with you because you just like your own definitions better than the ones everyone else is using and agrees upon. I'm sure everyone would be glad to switch to your definitions if they made any sense, but they don't.
Wherever you might stand upon the surface of this Earth, you are standing atop a geological column. No location is an exception, and the specifics of the strata underlying any location matter not. Sediment can add to any local geologic column anywhere, regardless whether that column includes deformed or eroded stata.

No, not just here and there. Its
everywhere. Every single point on the surface of the Earth has layers below it. Those layers below it are called the "geological column" for that particular section of the surface.
Each section will have its own column. Some sections are bigger than others.
I'll have to look it up but the layers aren't everywhere on the earth.
Yes, they are.
Everywhere.
There is no place on the surface of the Earth that does not have underlying layers. That's impossible. What would the surface be sitting on?
A Column is a VERTICAL Structure
The Geological Column isn't like a real actual "thing". Its an abstract.
It is a cross-section of what layers are underneath the ground at some particular place. Different places are going to have different columns.
If you took a giant metal tube, forced it into the ground, and then pulled out a big stack of the layers underneath, then you would have a column of the underlying geology. You could then study each layer to determine the properties of the past. Here's an example:

That represents the geological column at that particular site. If you traveled a ways away and took another bore sample, you would get a different geological column.
