So every element in our solar system that humans have ever seen

Actually the heavier elements weren't created by our sun. Heavy elements are created in the stages before a star goes supernova, and dies. Then during the nova all that material is flung out into space, and eventually some of it ended up here, and we built guns to kill each other with it.

To answer the second question, probably not. Odds are that if that could happen, it would during such a supernova, and then it already would have, since such massive stars have such short lifespans.

does OP say that there already was a star in our system before our sun was even born

This is the definition of star generations. 1st generation stars can only contain hydrogen, helium, and a tiny bit of lithium. Only later generation stars can contain heavier elements.

How did he lose the war with a gun that big?

>>7740762
he had only one testicle

Ah I see.

Theoretically yes, but I imagine that there is a high point for atomic size where you can't keep adding protons. I'm no physicist so I don't know if that is possible.

This.
There is a limit to the size of a nucleus.
At a certain point, the collective proton-proton electrostatic repulsive forces for any given proton exceed the attractive strong nuclear forces between adjacent nucleons.

You are also misunderstanding how the heavier elements are synthesized. I am almost certain that no star synthesizes anything above Z=26 (iron) during normal burning stages regardless of the size of the star. Higher atomic numbers are made during supernova explosions and brown dwarf interactions. Larger stars just burn primarily through the CNO cycle while smaller stars such as the Sun burn primarily through the proton-proton cycle. This is not my personal area of expertise, but I don't believe that I have told you anything wrong.

the gun was really ineffective.
