So, are you saying that there is no such thing as consciousness?

No, there definitely is. Though some philosophers admittedly have been silly enough to deny it.

Well, just to buzz you a little. If I believe that God did something and this influences who I am and what I do, doesn't this mean that God actually did it in my inner private world? Isn't it all a matter of individual perception?

No!

Even if our choices are somehow determined by the biochemicals in our bodies, we have the perception of free will and we make choices on a daily basis, we have dilemmas and existential crises. This is the world we live in and we deal with.

True.
