 You’re raising a set of claims that sit right on the boundary between science, philosophy, and personal belief. It’s worth separating them carefully, because not all “evidence” is treated the same way.

1) What counts as evidence for “life”?

In biology, “life” isn’t defined by one thing like breathing or a heartbeat. It’s usually defined by a cluster of features: metabolism, growth, response to stimuli, reproduction, and maintaining internal balance (homeostasis). A person in a coma, for example, is still considered alive because those biological processes continue—even if consciousness is altered.

So in science, life ≠ consciousness. That distinction matters for everything else you’re discussing.

2) Is consciousness produced by the brain?

This is an open philosophical question, but scientifically, the strongest evidence we have points to a very tight dependence of consciousness on brain activity:

• Damage to specific brain areas reliably changes personality, memory, or awareness (e.g., the famous case of Phineas Gage).
• Anesthesia can turn consciousness off and back on in predictable ways.
• Brain imaging shows consistent correlations between neural activity and subjective experience.

That doesn’t prove the brain “creates” consciousness in an ultimate sense—but it shows that conscious experience is strongly mediated by the brain.

3) Near-death experiences (NDEs)

Researchers like Bruce Greyson have documented NDEs, and they are real experiences. The key question is how to interpret them.

Current scientific explanations include:

• Reduced oxygen to the brain
• Neurochemical surges (e.g., endorphins, ketamine-like effects)
• Temporal lobe activity
• Memory reconstruction after the event

Some NDE reports include accurate details, but when tested under controlled conditions (e.g., hidden targets in hospital rooms), clear, repeatable verification of perception outside the body hasn’t been established.

So: NDEs are evidence of profound subjective experience, not widely accepted evidence of consciousness existing independently of the brain.

4) Hypnosis and “pre-birth” or “past-life” claims

Hypnosis feels convincing, but it’s also highly susceptible to suggestion and confabulation (the brain filling in gaps with constructed narratives).

Studies on hypnotic regression show:

• People can produce vivid, emotionally real stories.
• These often contain historical inaccuracies or information absorbed unconsciously (cryptomnesia).

Researchers like Ian Stevenson and Jim Tucker did document intriguing cases, especially in children. However:

• Many cases rely on anecdotal reporting.
• Independent replication and controls are limited.
• Alternative explanations (memory contamination, coincidence, cultural influence) remain viable.

In mainstream science, this is considered interesting but unproven, not established evidence of reincarnation.

5) Mediums and communication with the deceased

Mediumship has been studied for over a century (including by organizations like the Society for Psychical Research).

Consistent findings:

• Some mediums produce strikingly specific statements.
• However, controlled experiments often show:
• “Cold reading” techniques
• General statements interpreted personally (the Forer effect)
• Information leakage or subtle cues

When strict controls are used (double-blind conditions), accuracy typically drops significantly. There’s no widely accepted, reproducible demonstration that mediums can access information from deceased individuals.

6) Personal experiences vs. scientific evidence

What you’re describing—your own recordings, comparisons, and cases—falls into a category scientists call anecdotal or case-based evidence.

That doesn’t mean it’s meaningless. It means:

• It can be compelling on an individual level.
• But it’s vulnerable to bias, interpretation, and lack of control.
• It doesn’t meet the standard of repeatable, independently verified evidence required to establish a claim about reality.

7) The key tension in your conclusion

You said: “This isn’t a theory, belief or opinion.”

From a scientific standpoint, it actually is—because:

• The claims (pre-life existence, partial consciousness elsewhere, post-death continuation) are not testable in a controlled, repeatable way.
• They rely on subjective reports rather than measurable, falsifiable data.

Science doesn’t say these ideas are impossible. It says:
we don’t currently have reliable evidence that they’re true.

Bottom line

• We have strong evidence for biological life.
• We have strong evidence that consciousness depends heavily on the brain.
• We have intriguing but inconclusive evidence from NDEs, hypnosis, and reincarnation research.
• We do not have widely accepted scientific evidence that consciousness exists independently of the body or survives death.

If you want to push this further, the most productive direction is to ask:
“What kind of experiment would convincingly prove this?”

That question tends to separate what feels compelling from what can actually be established as evidence.
