Which religion will die out first Christianity or Islam?

probably Christianity

Christianity on earth will be gone seven years before Christ returns and us with Him

Christianity is quickly losing a lot of ground compared to Islam, so I'm going to have to say Christianity.

First Islam, then atheism. Christianity will not die out.

Neither will die out, they will evolve into a strange little cult where the dim witted will get together and talk about magic pixies and gnomes that tend their gardens when they are good. They will hope one day to transcend to the Great McDonald's in the sky. They will all worship the mighty banana that created everything in 3.5 days and played silly games with their emotions.

same time. they'll kill themselves off and leave the rest of us to do the hard work of building a livable world.

Its an interesting question because on the one hand many people are turning away from Christianity for various reasons (I know the whole pedophile scandal in the Catholic church has really damaged its numbers) so in that sense Islam is doing better. On the other hand we know that a lot of the strongly Islamic countries are also countries that are in the middle of war, considerably poor etc. When these countries finally are free from war and poverty I think you'll find the numbers of people actively practicing their religion will drop. This has happened all over the world and is relatively consistent, as countries become wealthier religion drops in numbers. Ireland is a great example, during the horrible recession in the 1980s the numbers attending church were huge. When the economy turned around and became very wealthy during the "Celtic Tiger" economy church numbers dropped massively. I still think it'll be many years before any of these religions actually die out though. Oh and Hail Satan! :P

Religions have generally been replaced by new religions that swell up in superstitious places. The more poor and uneducated, the higher level of superstition, so it will probably swallow Islam first.

Just a a decade ago I'd have said Christianity but now I see Christianity flourishing in spite of the odds against it. Christianity seems to be holding its own despite the massive ideological and physical attacks against. The only drawback is that if it survives we could end up with a militant version like during the dark ages.

Christianity of course buy not for a long time.
Islam however has the fertility God on it's side.

Since Christianity is not a religion, the answer must be Islam.

Christianity is a relationship with the one true, living God, Jesus Christ.
