But gravitational force is felt even if we are away from earth… Since gravitational forces have almost infinite range… We can feel it even at the moon… Though with not so much effect.

Inverse square law.
 
The gravity works, but not so much.
 
Think of it this way: Your mom’s always pressuring you to be a good child.
When you are home (small distance) you obey everything.
When you are in Delhi (bit larger distance) you start bunking classes and other stuff.
When you go abroad, your life becomes the Hangover Trilogy.

Your can think like that.. but on the other hand.  Earth is spherical and if the two objects are falling.. then they are not only coming closer to earth.. they are also coming closer to each other.. because they fall radically inward..  that makes that concept wrong.. a pseudo force concept.if there is a pseudo force.. that will be in only one direction.. but gravity acts radially inward..
