If a hundred different religions have to be wrong for yours to be right...?

No god exists. never has done.

No.

If a hundred different answers to the equation "2 + 2 = " have to be wrong for your answer to be right, does that show that people all over the world like to invent answers to mathematical equations?

YOU GOT IT, DUDE. From the beginning of time for us, Satan the Devil has been at his business of turning people away from the only true God whose name is Jehovah. The Bible book of Revelation tells us this about Babylon the Great, the harlot and world power of false religion. "Get out of her, my people, if YOU do not want to share with her in her sins, and if YOU do not want to receive part of her plagues. For her sins have massed together clear up to heaven, and God has called her acts of injustice to mind." Revelation 18:4 and 5 If your religion teaches anything other than what the Bible says, it cannot be the true religion. For example: the trinity which means three gods in one which actually teaches that Jesus is God. Where did this come from? I could tell you, but I would rather you see for yourself. The New Encyclopedia Britannica (1976) Micropaedia, Vol.X, p. 126 and The New Catholic Encyclopedia (1967) Volume XIV, p. 299 Also, I would like you to look into our website at www.jw.org. to learn for yourself what the false teachings of the churches actually are for your own educational purposes. "The truth will set you free." John 8:32

It shows that Satan is the author of confusion. Revelation 12:9 says:

And the great dragon was thrown down, that ancient serpent, who is called the devil and Satan, the deceiver of the whole world—he was thrown down to the earth, and his angels were thrown down with him.

He deceives everyone that he can to get them to look away from Christianity and the One True God.

What? one of the religions is right, whether its christianity or no religion but somebody has the correct idea about God and everyone else is wrong. i just follow the most credible option with catholic Christianity.

Not really , there can be some truths in many religions but one having the fullness of truth .

All religions have some truth to their beliefs. Some have more truth than others. Pray that God will lead you to the truth. Truth will make you free.

But Mercuri, there are tens of thousands that are necessarily wrong!

Forty thousand of those are just Christians.

One truth out there in the cosmic duck pong full of your (the Devil) enemy's decoys.

it just proves the masses of people want to be controlled so their life has some meaning because they cant handle the fact we are here to be here

That's a great big yes.
