Presupposing the truth of Christianity, atheism is morally wrong

My opponent claims that atheists have morally wrong standards because they do not worship God. However, if no God exists, or if creationism is false, this cannot hold true.How reliable is the Bible?Before you claim something is true because it says it in the Bible, you need to decide whether you can rely on it. For example, the New Testament is not variant-free. [1] Group of Writings Total Number of Verses Number of Verses with Variants Percentage of Verses with Variants The Gospels 3769 1713 45.4% The Acts 1006 329 32.7% Pauline Epistles 2032 495 24.4% The Catholic Epistles 735 220 29.9% Revelation 405 191 47.1% Total 7947 2948 37.1% As you can see, even the work with the least variants, the Pauline epistles, is 25% variant verses! One fourth of that group of writings is unreliable! And for the Revelation and the Gospels, almost half of each group of writings is corrupted. If the Bible is this unreliable already, why are you depending upon it to say that others’ beliefs are morally wrong? How do you know which verses are right and which are wrong?False propheciesAccording to Deuteronomy 18:22,“If what a prophet proclaims in the name of the LORD does not take place or come true, that is a message the LORD has not spoken. That prophet has spoken presumptuously, so do not be alarmed.”[2] In other words, if someone creates a prophecy in the name of the Lord that does not come true, he is a false prophet. Both Matthew and Luke quote Isaiah by stating that Jesus was born from a virgin birth. [3] But the question is, was Isaiah really a true prophet? Isaiah foretold the drying up of all the waters of the Egypt, and the destruction of all land used for plantation due to this drying up of the River Nile. Isaiah 19:5-7 “And the waters of the Nile will be dried up, and the river will be parched and dry; and its canal will become foul, and the branches of Egypt's Nile will diminish and dry up, reeds and rushes will rot away. There will be bare places by the Nile, on the brink of the Nile, and all that is sown by the Nile will dry up, be driven away, and be no more.” This part of Isaiah is about 2750 years old. And yet, this prophecy hasn’t been fulfilled in more than 2000 years! And from the context, it’s also evident that Isaiah’s prophecy was meant for the Egypt of his time; it was with that Egypt that Isaiah and his people had a grievance against, and the prophecy was a warning to them. This is a clear example of an unfulfilled prophecy. [4]Isaiah also said that the King of Judah would not be harmed by his enemies. Isaiah 7:1-7 “In the days of Ahaz,...king of Judah, Rezin the king of Syria and Pekah the son of Remaliah the king of Israel came up to Jerusalem to wage war against it, but they could not conquer it...And the Lord said to Isaiah “Go forth to meet Ahaz...and say to him, ‘Take heed, be quiet, do not fear, and do not let your heart be faint...at the fierce anger of Rezin...and the son of Remaliah. Because Syria...and the son of Remaliah has devised evil against you saying “Let us go up against Judah and terrify it and let us conquer it for ourselves...” thus says the Lord God: “It shall not stand and it shall not come to pass...” However, in II Chronicles, Syria and Pekah really did conquer Judah! [4] II Chronicles 28:1, 5-6 “Ahaz was 20 years old when he began his reign...[T]he Lord God gave him into the hand of the king of Syria, who defeated him and took captive a great number of his people...He was also given into the hand of the king of Israel who defeated him with great slaughter. For Pekah the son of Remaliah slew a hundred and twenty thousand in Judah in one day...” In that case, Isaiah was a false prophet. But he wasn’t the only one. Jeremiah also had a failed prophecy that said that Jehoiakim would have no successor. Jeremiah 36:30 “Therefore thus says the Lord concerning Jehoiakim king of Judah, he shall have none to sit on the throne of David.” However, according to II Kings, II Kings 24:6 “So Jehoiakim slept with his fathers and Jehoiachin his son reigned in his stead.”[4] And yet, despite the fact that the Bible contains many false prophets, many still rely on the book to say that others are wrong. Why depend on something so full of error? Because of the many mistakes in the Bible, Christianity cannot be 100% fact. We do not completely know which verses hold true, and which don’t. The Bible being so full of error, one cannot be sure in saying that atheism is morally wrong.
