Answer 1

Over 5000 Programming language are running all over the world.

Programs are just like tools for getting different results or performing different type of works.

In a car factory most of the tools are made from Steel but different tool works differently.

Same way in programs signs are more or less same but not written in same way.

Answer 2

Additionally, sometimes the technological advances or needs are so great that trying to use the existing languages is not interesting. For example, a long time ago, something like the 70's, computers had less memory than the size of one average document today. So the languages and programs had to consider this scarcity of resources. Nowadays, with our huge resources, we can develop languages and tools with other goals, such as easy of use, proximity to the real world, etc.
A simple x=5**3 would require several lines of code in Assembly; something like "select the first 5 customers with ages between 30 and 35 or credit>5000.67" would take several lines in Python or one line in SQL and so on.
