The questions are these: what form does that spirit energy take, and how does it interact with our ordinary atoms? Not only is new physics required, but dramatically new physics. Within QFT, there can't be a new collection of "spirit particles" and "spirit forces" that interact with our regular atoms, because we would have detected them in existing experiments. Ockham's razor is not on your side here, since you have to posit a completely new realm of reality obeying very different rules than the ones we know.
But let's say you do that. How is the spirit energy supposed to interact with us? Here is the equation that tells us how electrons behave in the everyday world:
Don't worry about the details; it's the fact that the equation exists that matters, not its particular form. It's the Dirac equation -- the two terms on the left are roughly the velocity of the electron and its inertia -- coupled to electromagnetism and gravity, the two terms on the right.
As far as every experiment ever done is concerned, this equation is the correct description of how electrons behave at everyday energies. It's not a complete description; we haven't included the weak nuclear force, or couplings to hypothetical particles like the Higgs boson. But that's okay, since those are only important at high energies and/or short distances, very far from the regime of relevance to the human brain.
If you believe in an immaterial soul that interacts with our bodies, you need to believe that this equation is not right, even at everyday energies. There needs to be a new term (at minimum) on the right, representing how the soul interacts with electrons. (If that term doesn't exist, electrons will just go on their way as if there weren't any soul at all, and then what's the point?) So any respectable scientist who took this idea seriously would be asking -- what form does that interaction take? Is it local in spacetime? Does the soul respect gauge invariance and Lorentz invariance? Does the soul have a Hamiltonian? Do the interactions preserve unitarity and conservation of information?
Nobody ever asks these questions out loud, possibly because of how silly they sound. Once you start asking them, the choice you are faced with becomes clear: either overthrow everything we think we have learned about modern physics, or distrust the stew of religious accounts/unreliable testimony/wishful thinking that makes people believe in the possibility of life after death. It's not a difficult decision, as scientific theory-choice goes.

Science is agnostic.
SEE https://www.youtube.com/watch?v=mJpYUxRL_3U
Science is agnostic means simply that it does not proscribe anything beyond the reach of the evidence. Once there is evidence then it falls within the realm of science. We don't disallow that evidence because "there is a rule that science must remain agnostic."
You can see this with evolution. Science is not agnostic with respect to theistic beliefs that accept special creation 6,000 years ago. The idea of creation with age requires that DNA was also created with the appearance of age. The idea that the "specially created" arrangement of DNA that allows lifeforms to exist just happens to coincide with a structure that falsely evinces common ancestry is a big pill to swallow, enough so that we can agree that it disproves the idea of creation with age.
Theistic evolution is not disproved. So you could say that science remains agnostic there. Though Deism is the only idea that fits it really.
So you see using the mantra that science is agnostic does not forbid the train of thought presented in the article by Sean Carroll. If you don't agree with his thoughts feel free to show where he is wrong and please provide your evidence and experimental results that support your position.
