If God does not created us who does? What is the meaning of this question for you if you are an atheist, it is same for us if gravity does not exist what does.
There is tens of probability to do that except gravity. Why is your reason of the source of your obsession about gravity?
Our obsession is SCIENTIFIC REFERENCES. These references also discard other theories.
scientific facts must be observable and repeatable. You are talking about gravitation but nobody see the "gravitional particles" but you are claiming it as an scientific reality. No it is just a theory that we don't need to believe it.
As we know that science for scientist meaning of "explaining something except contain a word about God".
For example. I'm believing the sky is blue because God want it to be blue. Actually God created to "water" as very little blue. Sky is water, water is blue so sky is blue. Science knows the sky is blue but can't say "sky blue because it is created as blue" because "creation" comes from God. So the answer is why is the sky blue is: "because of the light
refraction". Science using some terms instead of God for explain some matter can't explained by scientific way and using it as science. Gravity is one of them.
Why we have weight? Because of the gravitation. How is it occur? because "gravitional particles attract each other". So where is the "gravitional particles"? No answer. The possible answer is: "They are at there we feel but we can't see it". So what is difference with explaining something with God's want. There is no difference. It is just a free will free choice.
When science making mistake, then using another lie to defend other lie. For example , "if there is gravitation real, why falling down objects can't go over the speed as estimated? Answer: Because of air resistance.
Look the free falling down test of Felix. Lets calculate it together.
It was 39000 metres high and the top speed of 1342 kms/h speed.
Now lets calculate the estimated speed for 39.000 metres: V2=2gh ; V=(about)= square (2*10*39.000) = 883 m/sec = 3.178 km/h
It is estimated as 3.178 km/h but occurred as 1.342 kms. Then we accept the loss rate as air friction but why don't we accept as "the formula is wrong".
Fall down a ball from a bridge and you'll see it will not fall at the time you calculated. And you'll say it as "air friction". Yes i accept the air friction but it is not a lot of as estimated.
Actually air friction never calculated as with the observation. When do you mistake on a experiment, then give all of mistakes to air friction. Then it is true your result but actually you found the mistake of your formula and corrected it. It is wrong. The formula is wrong so you need something as air friction to correct your formula.
