What are rebuttals to the argument that Christians only worship God to give their lives meaning?

Many people argue that we only created God and religion to give our lives meaning, and that is why we worship God and other gods. However, we have to take into consideration that humans tend to worship everything, and it is in our nature, which is evidence that God exists. (If we are merely evolved from inanimate matter with no aspect of Design involved, why would we possess this big sense of spirituality, worship and believing in gods, when in reality believing in gods that do not exist does not matter and does not help us survive?) How can we rebut the argument that we only worship God because we want meaning in our lives and to give an explanation for our existence?
