Actually in what I believe - Advaita Hinduism, there is no birth or death. That is considered an illusion. No atom of my body has ever died in the past 13.78 billion years nor will it die in future with my death. Each atoms, wherever that might go, will be frolicking just in the way that it did in my body. Lights are always on, they cannot ever be switched off. Conservation of energy.
...and where does energy come from_________
The material / physical realm of existence did Not always exist.
So, why would atoms exist before the creation of the universe ___________
The Bible teaches that God had No birth, and will have No death. God being from: everlasting to everlasting.
If there is No Creator where does life come from ___________
I find life can't come from nothing. I think even science knows that life does Not come from non-life.
Scripture informs us that life comes from God's POWER, God's STRENGTH at Isaiah 40:26.
So, God supplied the abundantly needed dynamic energy to create both the invisible and visible realm of existence.
Seems to me at his death 'Adam's atoms' returned back to the earth where Adam started.
Returning back to the dust did Not give life to Adam elsewhere, just going back to non-life.
It wasn't atoms that gave Adam life. It was when God blew the ' breath of life ' into life-less Adam; that's when Adam's atoms came to life.
I think I can see a reason for the 'illusion that there is no birth or death'.
Scripture teaches us that ' eternity' is in our hearts.
In other words, for each day we can count we can count both forwards and backwards forever and ever.
This is because originally we were designed to live forever. Forever on Earth.
Satan and Adam disrupted God's design, but time was needed so we could be born and think who we would like as Sovereign over us.
