Why is silence so hard to deal with?

Why is it so much easier for us to live our lives with a lot of things going on all the time than to just be in silence?

We're constantly surrounded by 'voices' that are influencing us on how to think, feel, and behave. Movies, music, TV, internet, cell phones, and a never-ending barrage of advertising. There's always something going on, always noise in our lives, but maybe there's a connection between the amount of noise in our lives and our inability to hear God. If God sometimes feels distant to us, maybe it's not because he's not talking to us, but simply because we aren't really listening.
Nooma is a revolutionary product that is changing the way people experience spirituality - a series of short films (10-14 minutes long) about God and our lives. Like parables, they use the experience of our lives to teach about the fullness of life through Jesus, tackling issues like forgiveness, discipleship, and unconditional love.
