Can anything exist for an infinite time or outside of time?

If God wasn’t created by anything else and has always existed, as is often suggested, how long did he wait before creating the Universe/Earth/Humans?Surely if time goes infinitely back, and something had always existed, it would never get to any point in the future. It couldn’t, because it would have to wait for an infinite amount of time to get to any point in the future.So it seems impossible to me that anything could have always existed. It seems that everything, including time, must have a beginning.I am aware of the scientific view that it doesn’t even make sense to consider time before the Big Bang, because time started with the Big Bang. And I am aware of the religious counterpoint, that God existed outside of time and created time along with the Universe.But can anything exist before time? Does existence not require time?Thoughts?

Good question. I think Big Bang & Cosmology is the most appropriate forum because, although there's a religious aspect to this, I'm really looking for a scientific explanation.
