Those who would make the Creation account given in Gen 1 and 2 (and even the history thru ch. 11) in the Hebrew Bible a myth open the door for those who say that it is a myth that the Jewish people are God’s chosen people: the Jews created their own God and myth to compete with, and separate from, the other gods and myths of pagan nations. (What a powerful myth!) They would be in agreement — knowingly or not — with those who claim that there is no God who intervenes in human affairs, no center of the universe or of this spherical Earth, and that there is no “specialness” of any thing, not even human beings, whom God uniquely created in His image and in His likeness. God has a plan and a purpose for His creation, and redemption to accomplish it is at the heart of it from before the beginning.
But YHVH God has chosen this planet as His focal point in the universe which He created; He has chosen a particular man — Abram/Abraham — through whom He promised with a covenant and an oath a chosen people — through His choice of Isaac and of Jacob — and an inheritance, and to be a blessing to all the families of the Earth — and towards whom all people would be held to account; He has chosen a particular land — the Land of Canaan — for that inheritance; He has chosen a particular city — Jerusalem — within this chosen Land of Israel as His city; He has chosen a particular tribe — Judah — through whom the King whom He has chosen will establish His righteous kingdom when He comes again, with His elect saints, from that city in that land over all the Earth and nations; He has chosen a particular person of that tribe — David — to whom He promised in covenant and with an oath that this King Messiah would come from him; He has appointed one mediator between Himself and humanity — Yeshua the Messiah/Jesus Christ, the unique and beloved Son of God — and one way of salvation through the forgiveness of sins in order to be justified for inheriting all of these great and precious promises, and especially eternal life together with Him: repent and believe the gospel — that Yeshua died on the cross for our sins, was buried, and rose again the third day, all according to the Scriptures, which are Holy Spirit/God-breathed inspiration written through chosen men of His choice.
Our God is holy, and He is Sovereign. He is the God of Truth. Nor is He a liar or a deceiver, which the devil is both. All myths and false narratives will fail. This Heaven and Earth will pass away, but His word will never pass away!
