The scriptures repeatedly establish that the soul or spirit does not cease to live when the body dies.
The examples of Moses appearing at the mount of transfiguration with Jesus and Jesus' parable of Lazarus and the rich man have been posted several times. They can only be factual if the soul/spirit does not die.
The Scriptures don't establish any such thing. The transfiguration was a vision of the coming of Christ.
And after six days Jesus taketh Peter, James, and John his brother, and bringeth them up into an high mountain apart,
2 And was transfigured before them: and his face did shine as the sun, and his raiment was white as the light.
3 And, behold, there appeared unto them Moses and Elias talking with him.
4 Then answered Peter, and said unto Jesus, Lord, it is good for us to be here: if thou wilt, let us make here three tabernacles; one for thee, and one for Moses, and one for Elias.
5 While he yet spake, behold, a bright cloud overshadowed them: and behold a voice out of the cloud, which said, This is my beloved Son, in whom I am well pleased; hear ye him.
6 And when the disciples heard it, they fell on their face, and were sore afraid.
7 And Jesus came and touched them, and said, Arise, and be not afraid.
8 And when they had lifted up their eyes, they saw no man, save Jesus only.
9 And as they came down from the mountain, Jesus charged them, saying,
Tell the vision to no man, until the Son of man be risen again from the dead. (Matt. 17:1-9 KJV)
16 For we have not followed cunningly devised fables,
when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty.
17 For he received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased.
18 And this voice which came from heaven we heard,
when we were with him in the holy mount. (2 Pet. 1:16-18 KJV)
The parable of Lazarus and the Rich Man is not an actual event. It is a parable that Jesus told to the Pharisees. It is about the end of the priesthood. It's the last in a series of parables that Jesus told. There are way too many problems if we try to say this is an example of ETC.
