The origin of the universe as described in the Bible is--
God made it. How He did it or how long it took is irrelevant and does not fall within the scope of Scriptural purpose given that it is a) irrelevant to the purpose of Scripture which is a delineation of God's Plan of Salvation and history of carrying that Plan to fruition; and b) we would never be able to understand the explanation anyway were it given.
Christianity has no need to "appeal to more people." Those who arrive at Christianity are led there by the Holy Spirit, not because they are impressed by doctrines, beliefs, or practices.
LOOKING DUMB TO THE WORLD IS A GOOD THING!--It shows that Christianity is indeed God's revealed Truth,
"For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. . . . God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong. He chose the lowly things of this world and the despised things--and the things that are not--to nullify the things that are, so that no one may boast before Him." (I Corinthians 1:18;27-29)
A Christian's value system is different from that of those in darkness, thus a Christian would take your critique as a complement and a source of reassurance. Thank you!
