The first programming languages designed to communicate instructions to a computer were written in the early 1950s. One of the first high-level languages ever developed for an electronic computer was called John Mauchly is Short Code.
Who first started coding?
The history of programming languages can be found on this page. Machine codes that were manually inputted into early computing machines were the first known programming languages. Konrad Zuse developed the first real programming language, called Plankalkl (Plan Calculus), during the second World War.
Zeus is a language that can be used for the creation of procedures, which store chunks of code that can be used over and over to perform routine operations.

What was the first human language?
The relationship with human evolution, the origin of language and its consequences have been subjects of study for hundreds of years.
The fossil record, archaeological evidence, contemporary language diversity, studies of language acquisition and comparisons between human language and systems of communication existing among animals are some of the evidence that scholars need to draw inferences from to study the origins of language.
There is little agreement about the facts and implications of the connection between the origins of language and modern human behavior. There is no such thing as a theory of the origins of language according to these scholars.
This is because language is not a separate adaptation but an internal aspect of the human.
Language features change too quickly to be able to link all of the world's languages to a common mother tongue, so it's hard to make an inference with it.
On the other hand, all human languages rely on combining sounds or phones to make words, many of those sounds are common across languages, different languages seem to structure the world semantically in similar ways, all human languages recognize the past, present and future.
All humans are capable of learning and speaking a variety of languages, such as the famous click sound of some San languages of Southern Africa, but these are probably within the capability of all human speakers if they are exposed to learning that sound at an early age.
