Unfortunately, before you say that, Christianity would have to be a single thing. Instead it's thousands of things.
There are problems with that claim. One is that the bible portrays a God who is many incompatible things ─ a polytheist, a being who can't find Adam and Eve in the Garden or know the number of righteous in Sodom (or care about them, until they're drawn to [his] attention), whose Bronze Age morals are appalling (invasive war, massacre, mass rape, human sacrifice, slavery, women as chattels, religious intolerance, absolute autarchy and more).
A second problem is that if you're right then everything good or bad that has ever happened and will ever happen is exactly and only as God intended before [he] made the universe. There's no moral responsibility left over for humans, and the Christian notion of the Fall goes out the window.
A third problem is that if God is genderless, why does the Tanakh (albeit only once) and the NT (all the time) and the Trinity Doctrine, and the Creed, call [him] Father?
No, man wasn't created perfect, having neither immortality nor knowledge of good and evil. No one has ever offered a coherent meaning to 'created in [his] own image'. The early part of the Tanakh is at very best ambiguous about a soul, which is an idea developed later, and in its Christian form draws heavily on Greek tradition.
The cosmology of the bible is plain ─ the earth is flat, fixed and immovable, and the heavenly bodies go round it. The sky is a solid dome that you can walk on and to which the heavenly bodies are affixed, so that if they come loose they'll fall to earth. (Details

The Fall is essentially a Christian idea. There's no Fall in the Garden story, for instance.
This version didn't become available until the 4th century CE when the Trinity doctrine was invented. In the NT, Jesus never once claims to be God, and expressly denies that he's God on at least 17 separate occasions. Paul agrees with him.
This is the autarchy I complained of earlier, a dream of mindless obedience. It's a taste I don't share.
Always tomorrow ─ Jesus has had two thousand years to tidy up the place, but ─ nothing.
Still, I dare say none of that will worry believers.
