I’ve been told that you can only Photoshop something in front of an existing object, but not behind it – why is that? Also how does it work when something is photoshopped to match the background of the image – when that thing wasn’t even in the original image as the view was blocked? For example you photoshopped someone who’s standing in front of a tree out – how can you photoshop the tree back on that was originally partially blocked by the said person ?

It’s not that you can’t put something behind another thing, it’s that the… farther you go into the image the harder it becomes. It’s more dependent upon the skill of the user.
If you zoom way in to the borders between things in an image(assuming a photograph) the boundaries aren’t typically sharp. There are at least a few pixels’ worth of “blurriness” between them. The ability to match that blurriness without it being detectable is often difficult.
As far as “matching the background” do you mean removing something from an image to make it appear as if it were never there?
The simplest answer is you can copy the existing background onto the area you want to cover. If you have access to other imagery of the same thing that lets you see more of it, you can potentially make it easier on yourself by using that or finding similar imagery.
If you are limited to the pixels available in a single image, it’s potentially more difficult, but not impossible.
Artistry and skillful tool manipulation.
