I'm curious about that too -- but then again, it wouldn't be the first time they demanded that we do their homework for them.
Well the first thing we have to prove is the Bible. It is a book inspired by God, full of prophecy, some which is yet to happen, but much has already happened. To know thousands of years accurately into the future means supernatural knowledge. Let me give you proof of an event that will occur in the near future, and yet written thousands of years ago.
The book of revelation says that in the middle of the tribulation we will see a sign in the Heavens. In Genesis it says the stars, planets, moons etc are all there for signs and seasons. So let me quote the first part of Revelation 12.
1 And there appeared a great wonder in heaven; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars:
2 And she being with child cried, travailing in birth, and pained to be delivered.
If you get some good astronomy software such as stellarium (free), you can set yourself to any vantage point on the Earth. If you put yourself in Jerusalem and look up, then scroll through thousands of years, you will see something in Sept 2017. Virgo is right over Jerusalem, with the Sun on her shoulder, and the Moon at her feet. She has a crown of 12 stars thanks to Leo and some of our planets aligning with it. Now scroll forward slowly and watch the King planet (Jupiter). It travels across to Virgo, and enters her womb area. It actually moves around the womb three time before exiting between her thighs. Now scroll forwards thousands of years and you will not see this again.
Now revelation continues with
3 And there appeared another wonder in heaven; and behold a great red dragon, having seven heads and ten horns, and seven crowns upon his heads.
4 And his tail drew the third part of the stars of heaven, and did cast them to the earth: and the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born.
If you use such software at the date I stated, you will be amazed to see this too. I won't say anymore, the proof is there for a future event to be seen.
So amazing isn't it that this was written thousands of years ago and so very accurately. I thought it might be a coincidence, but as you go through the rest of revelation and look at the signs, they will all be there.
The tribulation is broken up into two halves, the second being called the GREAT tribulation. Each being 3.5 years and the second starting Sept 2017. It's easy to now calculate the start of the tribulation.
It might also be interesting if you learn what a lunar tetrad is. The next one is 2014. There is always a significant event in alignment with a tetrad. We saw one in 1949 which is when Israel established it's own government. There was one in 1967-1968 which aligns with Israel re-claiming Jerusalem. There was one in 1493-1494 and the Jews were forced out of Spain. Next year will be the 8th tetrad since 1AD and another will not occur for 500 years.
