There are no planets, God never states in the creation account in Genesis 1 that He created planets. God states He created the sun, moon and stars all lights
There are no computers; God never stated, in Genesis, that he created computers.
There are no painkillers, no antibiotics, no antidepressants; God didn't tell us that he created them.
There are no X-ray machines, scanners or modern day medical aids. They didn't have them in Bible times and we are not told that they were created.
I believe the sun and moon are convex disk. facing toward the earth
And it seems that you are ignoring photographs to the contrary because they do not support your belief.
People do know; you just refuse to believe the answer because it's not in the Bible.
The Bible is not a science textbook. God has given us, humans, the ability to discover how awesome his creation is. Yet you won't believe their findings because the Bible writers didn't mention them.
i know nothing about flying
Simple enough to find out; get on a plane. Or ask a pilot those questions.
The Bible never addresses this
Now you're getting it.
The Bible doesn't address a lot of things. Its purpose is to tell us about God.
It tells us THAT God made the world, not how or what shape/weight/size it is.
It tells us that he made people in his image - i.e. we are creative, can make things, have knowledge, investigate, have wisdom, a mind and will etc, etc. It does not tell us of all the things that humans would invent/discover in the future; that is not its purpose.
God's will and purposes are not advanced, furthered or achieved by telling us what shape the earth is and other scientific details. It's interesting to some, it doesn't hurt to study it; it has nothing whatsoever to do with the state of a person's soul and whether or not they accept, and trust in, Jesus. A person who does that will receive eternal life and the Holy Spirit. They will become a child of God, have every spiritual blessing in Christ and a guaranteed inheritance - all that, the Bible does mention. That will be true whether they believe the earth is flat, a globe, square, triangular or a dodecahedron. It will be true if they use things not mentioned in the Bible and wear modern clothes - or whether they wear only robes, and sandals and write with a feather.
I don't honestly believe that when we get to heaven and are with our Lord and Saviour we will care two hoots about what shape our old, fallen planet was. If we do remember, and discuss it, it will make no difference. There is no sin in heaven so no one will be able to boast and say "I told you so." I don't believe there is any shame in heaven either, so no one will hide away in embarrassment because they were wrong.
It doesn't matter - and won't matter.
