In general, new concepts are defined with old concepts -- for example, a square might be defined using lines and points. So in some sense, everything that can be proven is connected until you get to the very basic assumptions made about the system.
However, according to one of Godel's incompleteness theorems, not everything that is true about arithmetic can be proven. So it depends on what you mean by "everything"
A theorem (or lemma).

No. According to Godel's incompleteness theorem, in any mathematical system there must be statements that cannot be proven to be true or false. You simply cannot know!
There is no mathematical proof that definitively shows that God does not exist. The existence of God is a philosophical and theological question that cannot be proven or disproven using mathematical methods.
There is no universally accepted mathematical proof for the existence of God. The question of God's existence is a matter of faith and belief, rather than something that can be proven through mathematical equations.
Such a statement is called a theorem.true
False. It is proven to be true IF some axioms are assumed to be true. A mathematical statement can be proven to be true only after some axioms have been assumed.
Neither. A theorem is a proven mathematical statement. This says nothing about how easily it can be proven. e.g. the Pythagorean Theorem is easily proven, but Fermat's Last Theorem is extremely difficult to prove.
Theorems are important statements that are proved.
If has been proven by many scientists.
A mathematical fact is any fact which can be proven mathematically. Examples: 1 + 1 = 2 0 / 1 is undefined The limit of 1/n as n approaches 0 is infinity.
All the things. Anything you see, touch or hold. If it exists, then it's part of "everything" but scientifically speaking, everything cannot be proven or completely figured out.
