There is nothing which is proving any existence of a 'God' (whatever this might be) and which is pointing to creation except out of human fantasy.
About Christianity, we cannot even prove that Jesus did exist as a real human. Sources supposed to report about this person reported nothing.
About creation, a 'God' is NOT supposed to create something what we are now as humans.
We have eyes worse than those of birds,
we have a nose which can smell far less than any dog.
we have ears, which hear by far less than bats.
Not to talk about birds which can fly, but humans cannot, well at least we can run (not so fast and far compared to many animals) and we can swim a little, for sure humans are not better than many animals.
if it is really true that the human was created out of something, it was created as a rather weak creature full with programming errors as animals were created earlier than humans.

Compared to Christianity at that ancient time, Islam was very much advanced regarding science.
Already around 1000 Al-Biruni was able to prove that the earth is round, understood its size and position as not the center of the universe, and nobody, unlike in Christianity 600 years later (Galileo), was threatening him with death for publishing his research.
Biruni (973 - 1048) developed a new method using trigonometric calculations to compute earth's radius and circumference based on the angle between the horizontal line and true horizon from a mountain top with known height. He calculated the height of the mountain by going to two points at sea level with a known distance apart and then measuring the angle between the plain and the top of the mountain for both points. Biruni's estimate of 6,339.9 km for the Earth radius had an error of 0.0026 and was 16.8 km less than the current value of 6,356.7 km. The idea came to him when he was on top of a tall mountain near Nandana in India. He measured the dip angle using an astrolabe and he applied to the law of sines formula. He also made use of algebra in his calculation. A = Highest point of mountain B = Lowest point of mountain h = Height of the mountain C = Lowest point of true horizon visible from point A O = Centre of Earth α = Dip angle r = Earth's radius Solution: The angle AOC = α. AO=(r+h) is the hypotenuse in triangle AOC. r=(r+h).cos(α) Then the right side can be simplified to find r. r=h.cos(α)/(1-cos(α))
