... either there are zillions of universes... a new one being created with every er... action of any and all quantum particles where it could "act" in more than one way (think about that for a moment... that's a lot of universes being generated)...

There isn't any actual evidence that natural consciousness is particularly dependent on, and requires, uniquely quantum behaviors.
"Uniquely quantum behaviors"
That's a good way of putting it. There is no reason to believe that what people call "consciousness" (whatever that may be) needs uniquely quantum behaviors beyond the way that everything else allegedly behaves according to QM.
I think it very likely that consciousness does NOT require a 'quantum computer', i.e. using logic beyond classical computers because of entanglement of qbits. They're just so fragile, requiring extreme near absolute zero temperatures and really tiny, not evolutionarily robust or able to function at noisy wetware 300 Kelvin temperatures.
The thermodynamic relaxation to classical physics is extremely fast and very robust, which is why everything we commonly experience is not quantum mechanical.
As difficult as entanglement is to believe, as well as understand, it is a well established property of quantum mechanics. And some physicists are suggesting that birds and other animals might be using the effect to see and navigate Earth's magnetic fields.
The process could work via light-triggered interactions on a chemical in bird’s eyes.
Light would excite two electrons on a molecule in the bird’s eye, switching one onto a second molecule, but the two would remain entangled even though they’re separated.
The Earth’s magnetic field would alter the alignment of the electron’s spins and in the process alter the chemical properties of the molecules. Physicists suspect that the reactions would leave varying concentrations of chemicals throughout the eye, possibly creating a picture of our planet’s magnetic field that would allow birds to orient themselves.
The theory is still in its infancy, but biophysicists already have their eyes on a few chemicals that might enable the birds to detect entanglement.
One such chemical is called cryptochrome and its potential effects already being studied.
It’s thought that that correlated pairs form in cryptochrome in the presence of blue light.
A group of physicists from the University of California at Irvine also studied the European Robin’s ability to sense small quantum changes by tampering with the magnetic field surrounding the birds.
A robin was placed in a cage during migration season and then the physicists switched the polarity of the magnetic field around it. The test indicated that changes on the level of one-thousandth the strength of Earth’s magnetic field would impact the birds’ abilities to orient themselves.
Perhaps even more fascinating is that European Robins might do a better job of detecting quantum entanglement than physics labs currently can. A group of physicists from the University of Oxford have proposed that entanglement could last in a bird’s retina for 100 microseconds, whereas physicists have only been able to make the interaction last for 80 microseconds – despite cooling their experiments to just above absolute zero.
The studies have implications beyond birds as well. A number of fish, reptiles, insects and even mammals are thought to use magnetic fields to navigate.
The important conclusion suggested by the experiments is that microtubules - in particular, brain microtubules - are macroscopic quantum systems. Already this would be enormously important conclusion. To my personal opinion, the interpretation in the talk is not convincing at the level of details and TGD inspired modification of the proposal in terms of flux tube coordinate grids making possible TQC architectures with tubulin dimers defining bits defining in turn TQC program looks more plausible to me. A natural generalization of of 1-braid TQC to 2-braid TQC is also highly suggestive in TGD framework and could be seen as evolutionary step assignable to the emergence of microtubules. The interpretation based in Fibonacci conduction paths fails to predict correctly the number of resonances. An attractive interpretation for the resonance frequencies is in terms of phase transitions between A and B type lattices. If A type lattices can be generated only in heff increasing phase transitions induced by AC stimulus at resonance frequencies, one could understand their experimental absence and why super-conductivity like state is generated.

Clearly, to all common sense, this is counter-intuitive, but the two-slit experiment seems to confirm the cat to be both alive and dead, because of the interference patterns (bands of dark and light) obtained during the experiment.
