Is there such a thing as pure, formless, energy ? If there is, could that have been what existed before the Big Bang ?

No. Energy is a property, not something concrete that can exist by itself.

No, because again, such a thing doesn't exist.

According to current theory.

I suggest that mass is a property too.

As well as all current evidence.

For some definitions of the term "mass", yes, this is correct.

What does any of this have to do with the topic of this thread?

Our best current model is that the Big Bang happened at the end of a previous inflation era. But this is still an open topic of research.
