I'm one of Jehovah's witnesses and thought I'll quickly address the points you made, for the benefit of others, as some are inaccurate.
FALSE. We accept that Jesus is God,
in a certain sense (Isaiah 9:6, John 10:28, Heb 1:8), we simply do not accept him as the 'one God'. Scripture is clear that the 'one God' is the Father, this is according to 1 Cor 8:4-6 among other scriptures,
"there is no God but one...just as there are many “gods” and many “lords,” 6 there is actually to us one God, the Father, from whom all things are and we for him; and there is one Lord, Jesus Christ...", as we can see by the verse, only the Father is identified as the 'one God', not Jesus.
TRUE, we deny the trinity doctrine.
3. Deny Jesus’s bodily resurrection
TRUE, we deny that Jesus rose with the same body he died in, rather, we believe he rose in a 'spirit body', this is based on the fact that scripture explicitly states Jesus rose as a spirit:
"..So it is written: “The first man Adam became a living person.” The last Adam [Jesus] became a life-giving spirit.." (1 Corinthians 15:45)
"..He [Jesus] was put to death in the flesh but made alive in the spirit.." (1 Peter 3:18)
SOMEWHAT TRUE, Angel is simply a term relating to a spirit person (see Hebrews 1:7), Angels are spirits, Demons are also spirits as well as God himself. Anyone who is not the 'one God' is an angelic/spirit being, one of the only distinction between spirits is between a wicked spirit (fallen angel). Since Jesus is not the 'one God' he is a spirit being, we believe Jesus to be the highest being in the universe both prior and after his coming to earth after the 'one God' the Father.
5. They don’t believe in hell/no eternal punishment
HALF TRUE. We do not believe in a literal fiery hell, this is because it does not fit in with God's nature of love and because of many scriptures contradicting the notion of a fiery hell, for example, Romans 6:23 states
"the wages sin pays is death, but the gift God gives is everlasting life by Christ Jesus our Lord", if the wages sin pay is death, if we die without the gift of eternal life then our sins have been paid by out death, as the verse states, so it goes beyond Scripture and what God has revealed to state God eternally tortures us.
6. Only 144,000 will go to heaven
TRUE. We believe only 144,00 will go to heaven, everyone else will remain on the new earth mention in
"the new Heaven and new Earth" in Rev 21:1-5. Scripture is clear that the
'meek will inherit the earth' (Matt 5:5), and
"The righteous will possess the earth, And they will live forever on it" (Ps 37:29).
7. “Jesus“ was Lucifer’s brother.
FALSE, we do not believe Jesus is Lucifer's brother, it is Mormons that believe this, not JW's.
8. The curse of Adam/the fall was lifted after the tree.
FALSE, the curse to Adam is still in effect today, hence why we're all still dying since it was death that was the curse.
FALSE, we do not believe in sinless perfectionism, we can only attain perfection by means of Jesus Christ and being brought to perfection by means of him.
10. The Atonement. “Adam was perfect which required another perfect life to be sacrificed to balance the scales” This was the purpose of the tree, not to atone for sins of believers.
I do not understand what you said about the tree, but yes, we believe Jesus death was an equivalent/corresponding sacrifice in relation to what Adam lost, hence the reason why Jesus is called the
"last Adam" (see 1 Cor 15:45 and 1 Cor 15:22). We believe Jesus death
was to atone for our sins.
11. Eternal life for unbelievers. Billions will achieve eternal life without belief or obedience to God.
FALSE, only those who accept the ransom and worship God will attain eternal life, any unbelievers will not survive.
