One of the things that I think is a really big deal is the Bible being wrong about the end of the world. According to the Bible we should all be dead right now and this world over.
What Bible verse are you thinking of here?
For note that nothing in the Bible requires that.
For example, even though the "last days" began in the first century AD with Jesus Christ's first coming (Hebrews 1:2) and the Holy Spirit's pouring-out at the Pentecost in Acts 2 (Acts 2:16-17), the last days can still be the last three, roughly 1,000-year "days" (2 Peter 3:8, Psalms 90:4), of the seven, roughly 1,000-year "days" from the creation of Adam in roughly 4,000 BC to the future end of the present earth and the creation of the New Earth (Revelation 21:1), as in a new surface for the earth, in roughly 3,000 AD. So the last "days" can be the roughly 3,000 years from Jesus' first coming to sometime after the future Millennium (of Revelation 20:4-6), which Millennium (1,000 years) will be part of the last, 1,000-year "day" (2 Peter 3:8), which could begin at Jesus' future, Second Coming (1 Corinthians 1:7-8).
I don’t believe there is any such place as hell or any such person as the devil.
On what do you base your belief in the non-existence of the devil?
For note that God's own Word the Holy Bible shows that there is indeed a devil:
Revelation 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan,
which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
And note that even some humans (not you) are of the devil:
John 8:42 Jesus said unto them, If God were your Father, ye would love me: for I proceeded forth and came from God; neither came I of myself, but he sent me.
43 Why do ye not understand my speech? even because ye cannot hear my word.
44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
45 And because I tell you the truth, ye believe me not.
46 ¶Which of you convinceth me of sin? And if I say the truth, why do ye not believe me?
47 He that is of God heareth God's words: ye therefore hear them not, because ye are not of God.
