Because we weren't made in the XEROX IMAGE of God. We cannot photograph God, and everyone had a different 'drawing' of what he looks like. Even in the Bible he has been a column of lightning, of smoke, of light. He is described as unseeable, unviewable. Those who 'look' at God directly are vaporized from the intense 'glow' or radiation. Dozens of different descriptions in the Bible, and yet there are none in the Bible that describe him as a white male, 6'2", blue eyes, etc. Neither are there any descriptions of God as a nubian warrior, at least in the Bible.
How can we assume that 'image' means what we want it to mean? Especially when God is the creator and must be (logically, if nothing else) way beyond the understanding of that which he creates.
We even admit God works in mysterious ways, but we insist he looks like Santa Claus without the red outfit. Maybe he even 'appears' to us as what we want to see. But the point is that I just don't believe that the authors of that section of the Bible intended us to believe that the God of our entire Universe was limited to the physical form of an Earth dwelling creature who depends on water, earth, and a combination of gases to exist, and for only very, very short periods of time.
Think of the word 'image' and 'mind', or 'view', and see how much more sense that entire paragraph makes. And it changes not a thing about the word of God, it only changes our INTERPRETATION (or the one GIVEN to us by others).
John 14:8 Phillip saith unto Him, “Lord, shew us the Father, and it sufficeth us.”
9 Jesus saith unto him, “Have I been so long time with you, and yet hast thou not known Me, Phillip? he that hast seen Me hath seen the Father; and how sayest thou then, ‘Shew us the Father’?
