These are beings that treat planets like golfballs...planets that Galactus must consume to survive. And let's not forget that he is just a mere fraction of their size.
That's due to the inherent natures of his character. Galactus' power fluctuates widely.
Anyway there are certain points that I'll address.
. Galactus was warded off by a God Blast that a Celestial shrugged off.
Galactus was warded off by a god blast, but he was weak (this is apparent due to his diminished status....he was only a few feet taller than Thor and his size is commesurate with his power/strength at that time).
Characters that Galactus does battle with would get annhilated in milliseconds by the Celestials.
The Celestials have, again, to my knowledge, not battled anyone on the caliber of enemies that Galactus battles, with the exception of Ego. This is what I was talking about before in regards to the scope of their powers. When has a single celestial battled 1 individual, with the collateral damage destroying entire galaxies (Galactus vs. FP Tyrant)?
When has a single celestial battled 1 individual, where the conflict was felt across multiple dimensions (Galactus vs. Mephisto, in his realm)?
When has a single celestial contained the power of Abraxus, antithesis to multi-Eternity?

I believe you're referencing the planets that the One Above All and ziran the tester (or analyzer) were throwing at thanos. Galactus has teleported entire galaxies instantaneously across the cosmos, nevermind throwing planets around like golf-balls against a enemy at close proximity.
And let's not forget that he is just a mere fraction of their size.
We should also not forget that Galactus can alter his size at whim, which I do not believe the celestials have the ability to do, or if they have showed it.
Galactus has altered his size several times to large proportions. In fact in that same Infinity Gauntlet comic, Galactus is shown at the same size as the other celestials. In other instances he appears even larger.
Several more points. The black celestial, considered to be one of the three most-powerful celestials ever, used the power of Galactus to attempt to conquer the universe. So, to be clear, the black celestial did not use celestial tech or celestial power, but instead used Galactus, and Galactus alone, to meet his ultimate goals. That means capabilities of Galactus > capabilities of the third, or even the second-most powerful celestial.
Earth X, while non-canon, has Galactus defeating and destroying several celestials with ease.
Lastly, Galactus has the UN, which is part of him. If he so wanted, he could obliterate the entire celestial race with a gesture.
