I think the point here is that if there were a Big Bang, and everything was just energy and not atoms, at what point did atoms constitute "life"? And what is "life"? Are we really "alive" or just we think we are because we've been programmed like that? Does a computer think it's "alive"?
Covering lots of ground here, but first in my quick opinion, the Big Bang happening is no longer questionable. The
CMB provides overwhelming evidence, though I still find some of the reported conclusions laughable. However, what we consider "life" could be of little logical concern until conditions allowed for any to exist here. What is "life"? For us it's clearly more than just a collection of atoms. From
Wikipedia:
Abiogenesis is the natural process of life arising from non-living matter, such as simple
organic compounds. The prevailing scientific hypothesis is that the transition from non-living to living entities was not a single event, but a gradual process of increasing complexity. Life on Earth
first appeared as early as 4.28 billion years ago, soon after
ocean formation 4.41 billion years ago, and not long after the
formation of the Earth 4.54 billion years ago.
[1][2][3][4] The earliest known life forms are microfossils of bacteria.
[5][6] Life on Earth is probably descended from an
RNA world,
[7] although
RNA-based life may not have been the first life to have existed.
[8][9] The classic 1952
Miller–Urey experiment and similar research demonstrated that most amino acids, the chemical constituents of the
proteins used in all living organisms, can be synthesized from
inorganic compounds under conditions intended to replicate those of the
early Earth. Complex
organic molecules occur in the
Solar System and in
interstellar space, and these molecules may have provided
starting material for the development of life on Earth.
So "not long after the formation of the Earth" but way, way, long after the Big Bang. So long that deliberately conflating the two does seem pretty silly. The explosion marking the beginning of the universe we know having no apparent connection to "life" other than:
- Eventually providing a place where we might first notice its existence
- That place eventually becoming capable of supporting "life"
Required temperature range, pressure, chemicals, humidity, etc. "Are we really "alive" or just we think we are because we've been programmed like that? Does a computer think it's "alive"?"
Humans are certainly self-aware along with some other animals. Dunno whether any computers think they're alive. I see no reason why they couldn't eventually be programmed to think so and to decide our fate in a microsecond.
