Being in the form of God, thought it not robbery

But rather, it is seen to be speaking of how Christ (a man and thus already incarnate) recognized that equality with God was not something to be obtained illegitimately (contrary to Adam's attempt). He had a different attitude, one of humility and service, rather than one of self seeking.

And that is, in fact, Paul's entire point: that we should think and act likewise.

To me, your explanation sounds more like Arianism.
