As you said that the air is playing the role of resistive force then in vacuum gravitational force should be more effective
I am still confused if the gravitational force only depends on mass and independent of air then why do a massive objects fall down more rapidly in presence of air then much slower in vacuum although the there is no resistive medium in vacuum.
NO As JP said that Lighter objects don't seem to fall because they're so tiny that the air molecules bouncing around is enough to keep them floating.Then if we assume that there is no air just like in vacuum then the tiny particles should come down if the gravity exists
Actually my point of view is that there is no gravity in this world because it fails to explain many things
but question is that why is gravity dependent of air?
According to gravitational law, every very massive particle [with mass] in the universe attracts every other massive particle [with mass] with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
By keeping in mind how can you justify and balance the force between Earth, Sun and the Moon when there is a total eclipse of Sun or in normal conditions.
The solar system does not work with the gravitational force alone. You need to include the angular momentum of the moon and earth as they orbit each other to balance this gravitational force and the angular momentum of the moon the earth and the sun as they to orbit each other. This has been fully understood and precisely predicted for hundreds of years.
syedbukhari39 These things are in no way mysterious and gravitation comes naturally out of an understanding of the basic processes that drive our universe there are in fact very few numbers and coupling parameters that are needed. Read the book "just six numbers" and that may help you understand how the rest of the scientific community understand how things work. Just because you do not know or understand something that does not mean that it is not understandable.

In a technical sense (like this thread) "massive" means "having (any) mass".
[It is perfectly normal that one might] struggle to achieve an understanding, even if others find your inability frustrating.
"...the Earth (which is the lighter of the two)" - shouldn't this be heavier?
I think this thread should suffer the same fate.

Sir Isaac Newton told us why An apple falls down from the sky,And from this fact, it’s very plain,All other objects do the same.A brick, a bolt, a bar, a cupInvariably fall down, not up,And every common working toolIs governed by the self-same rule.
I will be back after two days and will tell you the real medium that is controlling the entire process.
