o yes sir they sure do,
but i won't agree with "to start making them believe in it again" that time has long gone, they say its time to believe in NONE, today 6 out of 10 Christians in the modern world do not believe in God, the same must be the case with our Hindu friends.
An old man and his son cannot be both god along with a third one, and then they all are 1, not 3, they went astray, they were on the correct path for some time but after the council of Nicaea their faith became a termite for themselves.
Our Creator is unimaginable, you make an image of Him and you are done, Lord of this Mighty universe don't need a man or an animal like shape.
what do science tell you? can't you see the mighty size of this world? the stars that we see today shining in the sky were actually there some billions of years ago and now they are at some other place, their light is reaching us today.
The Creator is too Mighty to have an image or any children or any assistant or rival gods, He orders "Be" and "it is", He is closer to us then our heart-beat is to us, He knows what every single cell of my body is doing right now, i don't
