Had Isaac Newton not created/discovered Calculus, would somebody else have by this time?

Same goes for other inventors/inventions like the lightbulb etc.

Absolutely.  There was a German mathematician named Gottfried Leibniz that discovered calculus simultaneously.  In fact, a lot of the notation we use today (such as dy/dx instead of y') is due to Leibniz and not Newton.
