[Various Godzilla movies]I would imagine that if an invincible monster hundreds of feet tall and capable of flattening cities showed up, people probably start worshiping it. How widespread is the worship of Godzilla and what are some of his religions like?

How did pre-existing religions respond to Godzilla?

Almost every culture in human history has a sun god, people tend to worship visible powerful things. It is hard to get much more powerful than Godzilla. One would imagine that his worship would become widespread quickly.

It varies wildly between depictions and eras. In most modern settings excluding shin and monsterverse and the original hes seen as a sort of protector of humanity albeit a highly destructive one. Most people don't worship him outside a few fringe lunatics but some see him as a sort of cleansing force of nature that avoids or protects them. Rarely does Godzilla attack unprovoked and he often defends humans even if it's coincidentally rather than purposefully. 

In shin Godzilla hes seen more as an abomination and a problem than anything god like or worthy of worship. Hes a leaking nuclear reactor melting down not a force of good or natural order.

Og Godzilla is just a straight up monster and death incarnate to people unfortunate enough to be in his way. No one worships him but lives in fear that the oxygen destroyer didn't kill him or that there's more of him out there.

Monsterverse he or at least his species was worshipped by ancient humans as a god. Modern humans see him as a deadly and dangerous threat but treat him as a natural part of the world now. Fringe cults remember his deeds stopping ghidora and the mutos but most remember the thousands killed by him and other titans. Only a handful of people don't want to kill him and most realize it's nearly impossible to kill him with human weapons so better to learn to live alongside him.
