How can Gravity Exist?

According to Newton:
“There is something called Gravity;
That’s why apples fall on to the earth!”

Yes, we accept; but can we prove?

According to Einstein:
“There is nothing as Gravity; but there is a Circularity of
Time in the Space!
That’s why all fall on to earth, including apples!”

We accept him as well; but can we prove?

The greatest philosopher has mentioned,
“Nothing is permanent, only impermanence is permanent;
There is no one as my self and nothing as mine!”

So, how can Gravity exist?
Can we prove it?
Not by blind beliefs…but by realizing
Reality of Life!
But when..?
