Where is Elijah and Enoch?

What happened to Elijah and Enoch? There has been an issue all over the internet, and i'm sure in many churches and households throughout the world concerning a couple verses within the bible with respect to Enoch and Elijah.

Enoch is the son of Jared, Enoch was the father of Methuselah, the oldest living person in the bible who died at nine hundred and sixty-nine years. Enoch his father, according to the bible walked in tune with God, and at the age of three hundred and sixty-five did not die, but was taken by God.

The question then is where was he taken to. The Bible does not mention much about the life of Enoch, but to say that he did not see death as he was translated being one who pleased God - Heb 11:5. He was the Seventh from Adam, and had Prophesied of ungodly men who would creep in among the saints turning the grace of our God into lasciviousness, and deny the only Lord God, and our lord Jesus Christ - Jud 1:14.

Elijah who was referred to as a man of God, also did not experience death. Elijah was taken up into heaven by a whirlwind - 2Ki 2:11. The word heaven here is believed to refer simply to the sky,  because the bible later mentions in St. John 3:13 - And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.

Therefore as no man has ascended into heaven, where might Elijah and Enoch be today?

Apart from the bible speaking of persons going to the grave to sleep until that great day of the Lord, it also speaks of persons going to another place called paradise from the following examples. In Luke 23:46 Jesus spoke to the thief saying today you will be with me in paradise. Therefore it would suggest that heaven might be distinct from paradise. This then becomes a bit confusing in 2 Cor 12:1-4 where the third heaven and paradise might be one of the same.

So the question is whether Enoch and Elijah are in paradise having not seen death, as the bible said no man have ascended into heaven, but he who came down from heaven
