Earth will die.
The magnetic poles of our earth are shifting. When the sun becomes a red dwarf star, it will consume and destroy the earth. The Andromeda galaxy is rocketing towards our milky way galaxy and will consume it. Why does school not teach these things?
Have you ever thought, before humans had language, what was the first (and consequently most important) thing that was communicated? Winter will end and return again in an endless cycle. This is the basis for all religion. Good and evil constantly fighting. Then someone was intelligent and discovered this cycle would eventually end. When a gnostic gains some pragma gnosis (practical knowledge) on higher understandings of life, they share it with all to improve all life.
Jesus is just a representation of the sun. Astrologers have calculated how the sky looks in the holy land in the times when Christianity was formed. Back then in the holy land on approximately December 25th (near mid winter), the sun barely peaks over the horizon and lines and lines up in the middle of 4 stars that form a cross (the southern crux). The sun then "dies" on the cross until resurrection next Easter. Whenever you see a christian cross with Jesus or Christ nailed to the cross, you will notice that Jesus has his hands "nailed to the cross" with the nails running through the center of his hands. If a human body was nailed to a cross in this fashion, it would immediately fall to the ground as it would not support the weight of the body. The hands of Jesus on a cross is just the representation of the stars Mimosa and Delta Crucis. The Christian religion is just a retelling of this story from other religions before Christianity existed. Horus/Osiris (Egyptian) Attis/Mithra (Roman) Krishna (Indian) Dionysus (Greek)
