You sort of wrote yourself into a corner there..... But, truthfully, 1.7 is no longer supported due to being so old, only the current (1.16.x) and previous (1.15.x) versions are supported. You will need to update to a modern version to receive support.

Alright so I don't really understand all the files and technical stuff so please don't answer with that. I saw a forum with the same problem where 1.7 wasn't working for him. He said that he manually installed forge and that worked. what does that mean and how do I do that?

I have done that, but I still cannot find a "EntityAttributeCreationEvent" event class or method anywhere when using intellij's search feature. Also when I try to run, I now get an error: BlocksReal's Block Creatures\build\tmp\expandedArchives\forge-1.16.5-36.1.6_mapped_snapshot_20210421-1.15.1-sources.jar_a6143e0dca70b177e5cb22179a0cd7b2\net\minecraft\entity\EntityClassification.java:40: error: method getName() is already defined in enum EntityClassification public String getName() {

[ne.mi.fm.lo.RuntimeDistCleaner/DISTXFORM]: Attempted to load class net/minecraft/client/gui/screen/Screen for invalid dist DEDICATED_SERVER" I think this one might be the Error, but I dont know how to fix that  

I can't. This computer doesn't support windows any higher. And. I don't like Linux. Just with no reason. Idc about the security, cuz my browser just stops me from connecting to unsafe websites, so i don't have to be afraid of getting a virus from the internet. Even if i got something, i can just dowload free version of Dr Web and scan the computer.
