Something big happened to the human race in Eden
The first use of the term 'big bang' was by physicist Fred Hoyle on a BBC broadcast in 1949 when he used it to contrast the Steady State theory to an emerging the hypothesis that all matter of the universe was created in one big bang at a particular time in the remote past, a concept he argued against and said was 'irrational and outside science.'
Special creative act. Spiritual life was cloning, not growth.
Best evidence: Bible, science, reason
No end to ideas and possibilities of what happened and how happened, but this interpretation is ... in depth below
Does not affect Christology, the core of Christianity.
Time estimates can be calculated from Bible genealogies
The Bible gives genealogies.
Spiritual life was added to physical life
Today, the big bang theory is the predominant explanation of how the universe began and is now generally regarded as settled science. The theory says that the universe started with a 'singularity' (Christians say 'God'), then exploded, expanding and cooling over the next 13.8 billion years into the cosmos we know today – and it's still expanding!
In the first second after the universe began, the surrounding temperature reached about 10 billion degrees Fahrenheit according to NASA, heat so intense that light could not penetrate it.
Did it actually happen, or a parable?
It doesn't matter.
Principle: Interpret the Bible for plain meaning and consistncy
If the big bang is the beginning of nature, then some intelligence outside of nature, and above nature, had to trigger the big bang, to start everything out of nothing, and to establish those predetermined laws of nuclear energy, physics and chemistry that enabled it happen with orderly precision.
Apparently billions of years passed between Genesis 1:2 and Genesis 1:3, as the earth cooled, became liquid, and eventually developed a solid crust.
Then God started shaping the earth and putting life on it. In the first stage of transformation, light starts glowing through the cloud cover, the basic energy for all life. The stages are summarized in Genesis 1:3 through Genesis 2:3 [see 1.2].
The compiler/writer of Genesis (generally thought to be Moses) could not have had this scientific insight more than three thousand years ago without some special revelation from God.
enesis 2 is another matter [see 1.5], outside the realm of science, because it's about creation of the non-physical parts, the parts that distinguish humans from animals ... our greatly enhanced soul (mind, will and emotion) ... our moral character ... and our connection to God.
There's no ME without soul and spirit.
