What if Jesus had failed?

[Sword of Christ]

They seem to have learned that from the Zoroastrian Persians. It is nothing by re-cycled shit.

They may have got the concept of Satan from Ahriman but the important difference is that Satan isn't an equal to God but merely a created creature who rebelled against God and encourages others to do the same. But the Torah/Old Testament is a history of the Jewish people specifically and their relationship with the one God of all that exists. Not just the Jewish people but everything and everyone in the universe. So that's some important exclusive content there. In Christianity that one of God the universe becomes a man so that's even more exclusive content there. Mohammed adds nothing new, he just remixes some of the stories, removes Jesus divinity and the doctrine of the Trinity, restores some Rabbinic Laws and introduces some Arabic Pagan practices. Don't even get started on what Joesph Smith did to it. What these prophets generally add is themselves, in such a way that it empowered themselves to get more women in the sack.

But why is it that when the Jews did it, it's a "twist," while the others are a deliberate manufacture?

The Jews were the first fully monotheistic civilized culture on Earth (though the ancient Egyptians tried it for 20 years). So while the story of Noahs Ark derived from the Epic of Gilgamesh it talks about Gods relationship as creator of the Earth, all living things, the environment and also the subjects of human sin and new beginnings, Gods wrath and Gods forgiveness are covered. You don't really get all this in the Epic of Gilgamesh. Killing practically every living thing on Earth accept for what was on the Ark was a little bit harsh yes but in the supplementary Jewish literature (Book of Enoch) he was trying to cleanse the Earth of the Nephilim who were the result of the fallen angels breeding with humans and corrupting their bloodline/DNA or whatever. Ascension of the Metatron is a pretty good video game based on the Book of Enoch if you ever played that.

Are you seriously trying to claim the achievements of all of other religions as those of your own? Do you have any evidence for this boldly presumptuous claim?

They're all achievements of mankind in union with the ultimate reality and source of all being and all that exists that is God. Christianity just gives you the full picture in Christ. No-one approaches the father accept through him, who is also himself God of course, the genuine article you could say. Jesus himself made this bold claim himself so if you're a Christian this is what you believe. Evidence wise you have the Bible, the Biblical prophecies, the resurrection of Christ and the empty tomb and the inner witness of the Holy Spirit. As far as scientific evidence is concerned you have absolutely nothing at all, not that there is any scientific evidence to support the bold claims of atheism either so there isn't really much for you to complain about. I'd say Christians have a little bit more evidence to go on if anything, something is better than nothing at all. Christianity as a faith may be mistaken but the claim that God doesn't exist or there is no good reason to believe God exists could also just as well be very mistaken indeed. If you want to compare Christianity to the other religions I think it more than holds its own in distinction, rather than it being a copy or rip-off. One of the central themes is that salvation is through the grace of God given as a gift rather than solely through your own efforts and works. You get that in no other religion.
