This only shows your ignorance. Do not comment about any religion without completely understanding it. Hinduism also believes in formless god (which is called "Brahmam") from whom all the avataras (prophets, in your language)have originated. But we pray to the avaataras or prophets as through them it is easier to reach God. This does not mean Hindus have no other alternative but worship the prophets or avataras. It is the choice of the individual worship God whichever way he wants, unlike other religions where you are bound by a by a set of rules and made to strictly follow what is being preached. Better to keep shut if your knowledge is not complete!!!!
