Well, first you must have the wherewithal to 'Remember' all the pieces of the puzzle and retain them in your memory so as to put them together and see the bigger picture. Don't feel bad, the vast majority of people cannot do this.
Mostly because of all the daily distractions in our world like the god of Television and all the mind-numbing nonsense that is fed to the masses via that medium. And partly due to sheer lack of raw intelligence.
And secondly, I hate to break it to ya, but I'm not here for your attention.
But I will have mercy on you and give you a quick lesson in Conditional If/Then Logic 101.
Now, focus:
1. IF the Bible tells us that God created 2 great lights in the sky that are independent of each other, one to rule the day and one to rule the night,
THEN we can 'Logically' deduce that the 2 greatest lights that we see in the sky with our very own eyes on a daily basis (almost daily for the moon, and almost daily for the sun for those who live in Seattle

) are 'Evidence' to the affirmative conclusion that the Bible is referring to the sun and the moon.
Still with me?
2. IF Joshua 10:12-13 tells us that Joshua made the sun and the moon STOP THEIR MOVEMENT ACROSS THE SKY directly over 2 specific locations that were roughly 10 miles apart, Gibeon and the Valley of Ajalon, (NOT that he made the Earth stop spinning)
THEN (if we have faith the size of a mustard seed and believe our Bible) we can 'Logically' deduce that the sun and the moon move over the Earth and not the other way around, AND we can deduce that they are MUCH closer to the Earth than science tells us today because it'd be hard for the sun and moon to stop side by side over the Earth 10 miles apart if they were the distance and size that science 'claims' they are.
3. IF we have come this far in our understanding/assumptions and we walk outside and see this:
THEN we can deduce that this is 'Evidence' to the affirmative conclusion that the sun is not very far above these clouds or the Earth and NOT 93 MILLLION miles away as science 'claims.'
4. IF we discover that there are flowers that exist on the Earth that only bloom/respond to moonlight,
THEN we can 'Logically' deduce that the moon is not a dead rock floating out in space 238,000 miles away reflecting the sun's rays back at the Earth and that maybe, like the sun, it is actually very near the Earth and gives off its own unique light.....just as the Word of God tells us it does.
5. IF we have made it this far and have begun to notice the flat horizon in the background of scenes in almost every movie made and every time we are at a place on the Earth where we can see a good distance like the beach or mountains, etc.,
THEN we just might 'Logically' deduce that this image of the world that is THOUSANDS of years old right here......just might be a bit more plausible than we'd previously ASSUMED.
6. IF we claim to be Christians and believe at least the 'basics' of our Bible concerning man being 'Created' by God and NOT evolving from wild beasts who evolved from swamp soup,
THEN we can 'Logically' deduce that man has ALWAYS been very intelligent, just as God created us from the very beginning, and any information like the Bible and this model of the world are NOT the ramblings of primitive cave men, and may very well have something very important to teach us if we humble ourselves enough to admit that we just may NOT know all there is to know.
Yea ok
rev. 6:16
They called to the mountains and the rocks, "Fall on us and hide us from the face of him who sits on the throne and from the wrath of the Lamb!
(For the record, the Bible was not written by men at all, but 'BY' God 'THROUGH' faithful men who dedicated their entire lives to His Truth and His Word and wrote down 'ONLY' what they were told to write by God, Himself. There are NO mistakes in the descriptions of the world or events in the Bible. If God didn't want it written 'Precisely' as it was written, it would NOT have been written that way. These men often lived decades to centuries apart and never contradicted each other's writings because the information was given to them by God.)
7. IF we are very brave and humble enough to challenge our own preconceived beliefs about the world we live in,
THEN we just might have the nerve to look into these things ourselves and do our very own independent research to PROVE what is true about the matter.
But be warned! Once you humble yourself enough to look directly at the Truth of these matters and decide you are willing to accept the Truth, whatever it may be, you may very well never see the world the same way again.
I will issue you a challenge with this provocative statement: There is much, MUCH more evidence of the Flat Earth model/concept than there is for the Sphere earth. And many, MANY experiments have been done to prove all aspects of the Sphere earth model/concept as well as the planetary dynamics of our solar system and FAILED repeatedly for centuries.
So, help yourself to a large slice of humble pie and make the commitment to research all the information from both sides until you come to a conclusion that you feel within your soul is the Truth.
Good luck to you and God bless.
