No. It took 3.8 billion years for life to start on this planet, and I very much doubt it has begun anywhere else at this point.
Since the "big bang" the universe has been expanding, meaning anything further away from us wouldn't be suitable for life any time soon. It will be a few more billion years before single celled organisms could spring up somewhere and even then it will take millions of years before what we can call animals/aliens could be formed.
By which time, Earth will be probably not exist any more, because as the Sun gets older, it will expand and it will cause Earth to be uninhabitable.
Science. :)

@Theyitis No, there is no centre.
But they know which direction the explosion happened in, since the universe is still expanding in that direction. They also know that there's nothing from the direction of the bang.
