Actually, what we speak is rather closer to English than your own version.
That's distinctly moot. There is a good argument that American English has in many ways diverged less from the English of the early settlers than 'English' English has, the latter strongly influenced by imported language from other cultures, notably from India, but also from America and Australia and African Caribbean and so on.
Australian English was quite strongly influenced by Irish migrants.
The consequence is that it's hard so say which of those dialects is closest to 'true' English, whatever that might be.
We should celebrate both the differences and the similarities.
