ELI5: How is it even possible to just create a CS language out of nothing or out of an existing language?

How was the original binary code made where a computer could understand the code and produce an end result? 

How can someone just take one CS language and create a new CS language like Python? How do you teach the computer how to understand and execute the code or commands you create? 

I have very little to no CS background so I need someone to ELI5.

A computers CPU is like its brain. That's the part that actually processes the code.

When CPUs are designed, they are setup to take in specific binary code, and output specific output. It's literally built into the hardware. Like the binary code 0101 may tell the processor to store the next byte in memory or 0110 may tell the processor to add the next byte to the byte thats in memory.

Once you know the binary code that the processor needs, you can write a human friendly language pretty easily. All you need is a compiler, which is like a translator. It takes the human readable code and converts it into binary for the CPU to use.
