Seek GOD and you will find - not the shape of the earth, which is unimportant.
While I don't want to undermine your sentiments of seeking God first, since I love that heart cry, I will have to say I feel a strong urge in my spirit to defend these who seek the "truth" concerning their world.
If Lord Jesus is "...the way, the truth, and the life: ..." --- The truth concerning our world does indeed matter as God does not approve of lies and is not the father of them.
John 14:6
John 8:44
I know of a great, great number of people who have come to faith and believing in Lord Jesus through seeing their world clearly.
...And many who are still arriving on that very boat of truth pertaining to the place in which we live.
This is absolutely at the top of God's list of heart priorities. Seeking and saving all who would is His idea and will, not ours.
Luke 19:10
1 Timothy 2:3-4
God's children have a right to know where they live and a right to have lies exposed if they have been told them.
I don't think it a subject that division and strife should be caused over it.
2 Timothy 2:14
I've been on this journey for over twenty years. I don't expect anyone to understand the importance of this right off.
But I certainly would hope God's people would come around to agreement that the truth should be told about all subjects.
With that said............
This is not, in and of itself, a salvation issue and many people never even consider these things and maybe God didn't intend for them to.
But to flip that coin over, there are children of God, and people and soldiers revealing truth in every aspect of this world.
The Lord Jesus Christ Almighty owns every square inch of it, and I am not called by The Lord to judge His servants in their calling and specialties.
Romans 14:4
(admittedly some callings and specialties are more odd lol - there are deeper topics than these)
The shape of the earth may mean nothing to you. But to other people in the world God uses these truths to bring salvation to them and often their entire house-holds or friend-groups.
God never has fit very well in the boxes we sometimes as limited creatures unintentionally try to put Him into.
