Fallen man not only does not seek God, he flees from Him. He's not semi-fallen or quasi-fallen; he's toast.
Through God's gracious gift of regeneration we are born again, desiring only to "glorify God and enjoy Him forever."
At the center of that gift is Christ's sacrifice on the cross, wherein He suffered in our place, and washed our sins away forever.
If Man is actively fleeing from God than how do you explain the universal need of Man to connect with God (or a god if you prefer). The other religions are false, but they are still Man attempting to encounter the Divine.
