The evidence is that they are extremely unreactive, even under vigorous conditions.
Their valences are complete, thus they have no "need" to react.
And noble gases are found in nature...the first noble gas helium, is a component in our atmosphere while the heaviest noble gas radon, is a problem in many buildings because it accumulates after working its way up through the ground.

First is the theory that states that noble gases will not reacte because they have the outmost layer of electrons completely fulll.
Second is the fact that after more than 100 years of trying only a handful of exotic compounds containing noble gases have been discovered, all of them made under very extreme conditions.

because they dont react with very many things at all. there have been chemicals formed from noble gases and other substances, however, so the statement that "all elements bond to be more like the noble gases" is an absolute lie.

They don't react with hardly anything and they have a full set of valence electrons which makes them not want to gain or lose any in a chemical reaction with other elements.

They have 8 valence electrons and they don't need any more or less to be stable.

Very few noble gas compounds are known, and virtually none is found in nature.

Decades of experimentation and research and supporting theory.
