How Did Arithmetical Numbers Come Into Existence?

The primitive notion of numbers appears to have evolved from the many physical contrasts prevalent in nature - the difference between one tree and a forest, one sheep and a herd. Consequently, there was recognition of an abstract property shared by some groups: that ability to be placed in a one-to-one correspondence with each other. This property is what we now call number. Those groups which could not be placed in one-to-one correspondence did not share this property and are thus said to be different in number. Out of this realization of "sameness" was born the concept of number in mathematics.

The first known use of numbers dates back to around 30000 BC when tally marks were used by Paleolithic peoples. This system had no concept of place-value (such as in the currently used decimal notation), which limited its representation of large numbers. The first known system with place-value was the Mesopotamian with base 60 around 3400 BC and the earliest known decimal system dates to 3100 BC in Egypt.

The presently used arithmetic number system follows the Hindu-Arabic numeral system which is a positional decimal numeral system documented from the ninth century AD.

The cavemen mostlikely made "numbers" with scratch marks, then the Chinese took a take on it. Thus, we got our first markings soon to be called numbers. Though no one on Earth alive really truely knows the mastermind behind our common everyday scribbles that we seem to be lost without. Take for instance: time. What time is it? Why, it is 6:09 p.m.! And that right there is an example! So, really, we can't survive without 'em. They have movies made after them, scientists whose experiments depend on the sometimes confusing numbers, and us, who say and write them everyday. It doesn't matter where they are from, but where they're going in the future. Let's be more concerned about that.
Thank you.

Yeah see maths started when people wanted to count

I have heard that number came from the angles in the formal qualities of the numeric form. For example one has one angle. Two has two angles and so on. What about seven? Well it works if you draw the line through seven that many people used to make.
