Hello

Who can fairly briefly and intelligibly, explain how the bitcoin was born and how was its network launched?
You can do a research about this and that's better!
I've tried, too much extraneous information, or absolutely incorrect. Therefore I decided to ask for help from people more competent in this matter.
I am a newbie I'm not familiar of this cryptocurrency but I'm willing to learn because I can see this for a good future . I ask for help from my friends who is a investors of bitcoin. They give me a hint of what I am supposed to do.
