We have to look backwards:
I am here now, I existed 10 hours ago, I existed at 2 years old, I existed in my mother's womb, I existed at the time of conception, I existed in my previous life prior to conception, I existed in the years of my previous life, I existed at the time of conception in my previous life... and it goes on, and on, and on.
There is no beginning. It just hundreds of thousands - countless number of lifetimes. We are not actually born, we don't actually die. It's just a continuous stream of existence. There is no beginning.
The sheer thought is un-phantomable.
So who created us? If we break down our existence, we are our consciousness (as our body is a mere vehicle). If we are our consciousness, what is our consciousness?
