Most people who, "believe in," [read: "fervently wish for"] life after death do so because they have made a complete botch of the one life they'll ever have and, "hope," they get a second chance. It's very sad, because most of them waste the one life they actually have pursuing what they never will have and would screw up just as badly as the one life they have if they did.
Speaking for most people is more than a tad assumptive. So, what do we know for sure, and from that what can be implied rather than assumed?
What are you talking about? I'm not speaking for anyone else, just reporting what all those who pine for another life say themselves. They report they believe in another life that is superior in every way to the one they are living, and I'm only pointing out, that an individual's life experience is determine by what they choose to do with their life. If they don't like this life so much, they are willing to give it up for some promised future life they are admitting their life in this world is not the success it could be.

Consider:
- Light is a form of energy that has no mass.
Well, that's wrong. A photon has no, "rest mass," but
a photon is never at rest:
The vanishing of the rest mass, m=0, doesn't mean that photons don't carry any energy or "relativistic mass". Instead, it means that
E2−p2c2=m2c4=0
i.e. that the energy E is simply equal to |p⃗ |c where p⃗ is the momentum and c is the speed of light. It's the momentum and energy that must be nonzero for us to be able to say that "something is out there" and indeed, they're nonzero for each photon around us.
You may also say that the "total relativistic mass" of the photon is nonzero and equal to mtotal=E/c2. In some sense, this nonzero quantity measures the gravitational mass as well as the inertial mass (resistance to acceleration). We usually don't use the term "mass" for this quantity and prefer to talk about the energy E=mtotc2, reserving the term "mass" for the rest mass defined above.
The fact that the photon's rest mass is zero means that there isn't any "rest frame of a photon". Such a rest frame would have to move by the speed of light relatively to any proper inertial system and with such a fast motion, all the factors such as γ
would be singular and ill-defined.
Or consult any advance physics book. In, '"light," of that, the rest of what you say is nonsense.

- Life is also a form of energy that has no mass.
Life is not a thing and it certaily isn't energy. Life is nothing more than
an attribute of some physical entities called organisms. It doesn't, "do," anything. All behavior of physical organisms uses physical energy (because there isn't any other kind) and that energy can be measured.

- What we see when we see life, is life animating a particular ordering of matter.
You cannot see life. life is not a physical attribute, though it is an attribute of a physical entity--a physical organism. But life, consciousness, and human minds, though perfectly natural attributes, are not physical attributes because they cannot be directly perceived (seen, heard, felt, smelled, or tasted). You can observe the behavior of living organisms and observe that behavior is different from mere physical entities, but you cannot see the life attribute itself that makes them different.

The question is, how is it that matter gets configured into a particular form that science labels, a higher order of life?
- In other words, how does order rise from entropy, and even get legs to start walking?
Life doesn't, "arise," from anything. There is no difference in the physical nature of a living organism and a non-living physical entity. The difference is the presence of absence of the attribute life. Unless you believe in abiogenesis, life only comes from life.
