If the Bible is written by God then why only say Sun & Moon are lights, when they also make Tides in the oceans and the atmosphere?

You need to go no further than this part of your question: "If the Bible is written by God"

It wasn't. It was written by men, claiming to speak for God. Some had some relatively good ideas about morality. You can also point to a few that were reprehensible, like the allowance of slavery. If God could say thou shalt not covet thy neighbor's goat, he could have certainly said thou shalt not own a human as property. But, there is no such prohibition.

It may have pushed people forward in some small ways, but there’s nothing groundbreaking, nothing that couldn’t have been said by any decently intelligent person of the age. It gets some things right, and in some cases what is said is unintelligent or immoral.

The Bible is not written by God.

The Sun and Moon are lights. Do you think that is wrong?

The Bible doesn't teach anything of the sort, "The Sun and Moon are lights, only lights, and nothing more than lights."

The "bible" was created by man who selected, edited an compiled folk lore from several gospels from Christian based beliefs to present their version of Christianity and god in a vain attempt to solidify the church in the fourth century.

The account in Genesis is the restoration of those lights and their functions, NOT the creation of them. The first verse of Genesis tells us that both the heavens and the earth were created by GOD. By verse two we are already introduced to the earth in a 'formless and void' state where two great waters separated by temperature rise up to the height of the firmament. The 'deep,' also referred to throughout scripture as the 'abyss,' the 'bottomless pit' and the 'untraversable chasm' is also mentioned here as the location where GOD's Spirit 'hovered.'

The lower waters, (Hebrew: 'mayim tachath'), were in a liquid state up until a freeze point where the upper waters, (Hebrew: 'mayim al'), began and extended up to the edge of the 'abyss' as a giant frozen ice block. GOD had destroyed all life using these waters. When GOD said, 'Let there be light' He was commanding that the giant ice block be removed. The only place left to send it was what modern people call 'space.' This released the lower waters from its icy grip, after GOD commanded great chasms to be opened up to receive them. These chasms filled, watering the earth through subterranean springs until building up enough atmospheric moisture to restart the rain cycles. This is when GOD placed mankind in what He calls His 'Garden.'

The natural functions you describe are inevitable processes based on the laws which govern the Creation. That is why GOD had no need to separately give commands regarding them. All that was necessary was to remove the giant object that was blocking their light from view and interfering in their full natural function.

Why would GOD exclude our full history and the earth's origins, other than to say that He Is the Origin? For the same reason He commanded us not to explore the mysteries of the forge beyond copper implements and weapons. That also seemed unreasonable to mankind, so they ignored it, immediately trapping themselves inside of an inescapable arms race, pervasively poisoning the entire planet and being compelled to produce weapons of mass destruction just to survive. That is NOT a source of personal pride for me, but an important moral lesson.

When GOD says something I OBEY. GOD says not to explore the origin of the earth beyond recognizing that He created it. Wisdom respects this and lives. Knowledge does not. Wisdom embraces humility while acting intelligently. Knowledge embraces arrogance while acting foolishly.

The Bible isn't an encyclopedia. It's a collection of books about God. It also contains no information about programming in Fortran or landing procedures for a 747 or the strange success of My Little Pony: Friendship is Magic. But I don't see these as a sign that the Bible isn't from God. I see it as a sign that these things have absolutely no relevance to the subject.

You really seem to expect too much from the bible. It is there to teach religious truths. It is a history of the Jewish people, their prophets and the development of their covenant with God. It is also the memoirs of the Apostles of Christ with His words and teaching. It is not there to expound geology, or teach you about earth sciences. There are other books for that purpose.

god doesnt know science

The early hebrews didn't know that luna reflects light from sol.

The bible is not a science book.

Unless I want the Genesis creation story taught in science class, then it is.
