Transcendental infinities and infinitesimals - many different types of infinity exist, both countable and uncountable.

Most people tend to stop at the standard infinity that lies at the top end of the real number line - "bigger than the biggest number you can think of, and then some, plus one."

Never mind that there's another infinity, just as big, at the far end of the negative side of the real number line, and further infinities in all directions when you bring in complex numbers, quaternions, infinitesimals, the uncountable infinities lying between any two arbitrarily chosen adjacent real numbers and so on.

Also, the "Arabic" number system was invented in India. It was only introduced to the West by the Muslims.

Yes, America, if not for Muslims you'd still be counting in Roman numerals.

Please define "exist" as you've used it in your opening sentence.
