Surrounding the planets usually exists the various atmosphere. Due to this atmosphere, one light ray crossing the planet will be refracted more if it comes more closely to the planet's surface. So how to know that " gravity field phenomenon is the curved light ray" is not created by the planets' atmosphere ?

You forgot to ask why there are atmosphere around a planet in the first place.

There's one simple way to check for this. Put an object in an environment of "less atmosphere" and check its weight. If it has changed considerably as you pump out the air, then you'd be correct. I have a vacuum chamber that can go to as low as 10^-10 Torr. How much are you willing to bet that a block of, say, OFE copper that I put in there would be reduced in mass as I pump it down?
