Like others have said, if you're not a physicist, it's not really your job to explain the big bang. You can, however, explain to your friends WHY the evidence that supports the big bang makes sense to you.
Basically, the detection of cosmic radiation coupled with the fact that all galaxies, to this day, are still moving away from one another, suggests that at one point everything that exists expanded from one point and is still expanding today. It is sort of a hard concept to understand because, as far as we know, neither time nor space existed outside of this "point" or singularity... so the universe didn't really expand into anything, it just sort of expanded outward into itself, from itself. There is no edge or center to the universe because the universe
That is, at least, my elementary understanding of the idea and it's very possible I'm getting something wrong there. The idea makes sense to me.

There's plenty of info out there on the big bang that explains the evidence in an easily understandable way. Maybe look up some other youtube videos on the subject.

“Love is the only bow on Life’s dark cloud. It is the morning and the evening star. It shines upon the babe, and sheds its radiance on the quiet tomb. It is the mother of art, inspirer of poet, patriot and philosopher.
It is the air and light of every heart – builder of every home, kindler of every fire on every hearth. It was the first to dream of immortality. It fills the world with melody – for music is the voice of love.
Love is the magician, the enchanter, that changes worthless things to Joy, and makes royal kings and queens of common clay. It is the perfume of that wondrous flower, the heart, and without that sacred passion, that divine swoon, we are less than beasts; but with it, earth is heaven, and we are gods.” - Robert. G. Ingersoll
