Modern Astronomy isn't a science, since I can't create a star in the lab

A star is nothing more than a large fusion reaction, and mankind has created such reactions. They are called hydrogen bombs.

Not all stars are fueled by hydrogen fusion. Your post is incorrect and pointless. Astronomy operates by observation and inference, not by experiment.
