Now up until to day I believed in the heliocentric theory but now I am not so sure. Please help me out.

The best proof is the astronauts who have been in space and our space satellites observing the motion of the Earth orbiting the sun.. But if you were strictly Earth-bound, you would notice that the movements of the planetary bodies in space support the heliocentric theory. Just as an example, retrograde motion (where a planet appears to stop and reverse its course) or the fact that planets disappear behind the sun for a period of time (b/c they are orbiting the sun and not the Earth; if everything orbited Earth we could see them all the time). Just a couple of things to offer you proof.

Very creative way to get us to do your homework for you, rather than just typing the question.
The heliocentric theory states that the Earth and planets orbit the sun which is at the centre of the solar system.
Then Keplers Laws of planetary motion helped refine the heliocentric model - the sun is not at the exact center of any planet's orbit, but at one focus of the elliptical orbit.
Science compares the theory to the actual observations - when observations match what the theory predicted, scientists are relatively confident the theory is accurate (as far as the technology of the time allows).
One roof of the heliocentric hypothesis was provided in 1838 by Friedrich Wilhelm Bessel. Bessel proved that parallax of a star was greater than zero.
And the idea that the sun was not the center of the universe, but one of innumerable stars, was strongly advocated by Giordano Bruno and has been proven by astronomers over the past 3 centuries.

The Sun is the center of our solar system. This is the Heliocentric Theory developed by Nikolas Kopernik, a Polish scientist from the 1500s. (We usually call him Copernicus.)
The Sun is Not the center of our galaxy or of the universe, though.

Yes, travel to other planets by space probes and pictures from them on the way prove that.

Yes, it is very much true.
-
It's no longer just a theory.

You're "not so sure"? Just what do you think is true?
