That is: Why is the teaching of one THEORY, more important than the teaching of a different THEORY!

One theory has about 150 years of fulfilled predictions behind it. The alternative hypothesis is highly unlikely to ever make a prediction. One theory, in other words, is necessary to understanding what has happened and is happening. That alternative hypothesis thing isn't necessary at all.
