Aging is the condition of existing at all, a condition we share with all life across all time, with the galaxies and the entire cosmos.
Life itself is not aging. Sexual reproduction manages to regularly reset the aging clock by building a new organism from already existing cells, there is no discontinuity in life.
At some point, the mother and her child are the same organism.
Biology is already immortal, but the resetting process is quite lossy.
I am pretty sure that at some point our biology can be hacked to perpetually rejuvenate, in this case our bodies would look like 25 years old, not centenarians.
Evolution is inherent to the universe, and our spirit yearns for it.
It is not. Change and entropy is. And what is more change than death and dissolution of your physical body?
Life is anti-entropic, and acts in the opposite direction than the universe itself. But eventually entropy has to win, for it is the universal law.
Entropy decreases in lifeforms and increases in the universe. The former process helps to accelerate the universal rise of entropy, so is entirely consistent with the universe.
In the end, according to our current understanding, yes, entropy rises until it consumes all energy, and no more life is possible, but that is many trillions of years in the future, and until that time, the nature of the universe is to create ever more sophisticated life.
What you ascribe to universe, I ascribe to nature, as seen on Earth and, as far as we know, nowhere else in the universe.
The universe doesn't evolve. The universe doesn't create sophisticated life. It just is, and changes, and moves toward entropy. Nature is just a very small and very young system within that, by pure chance or other unknown factors, has managed to move a little upstream.
There is good indication that evolution began long before the Earth, and the classical life on it, emerged:

But you're assuming a state of affairs that we dare not even dream about yet, and spending it all on your hobby horse. There are other, more urgent needs, right now, on this planet. We should not allocate resources to the whimsical needs of a hedonistic few.
All humans on Earth could fit in a city with NYC's population density covering an area the size of Texas, which is only 0.48% of the Earth's land area. We could massively increase living space on a given area of land by building vertically as well.
And outside of Earth, in the rest of the solar system, I think you don't understand how much space and matter there is.
In terms of energy, I suggest this:

>>For each photon of light that strikes the Earth from the Sun, around two billion miss it. Say that, using the materials of the solar system, we can practically harvest only 1/1000th of that solar output. That would still leave an opportunity to increase our energy budget as a civilisation by a factor of 2,000,000 - a population of 16 trillion each consuming 1000 times as much energy as the average person on Earth does. That figure includes the energy required to power the biospheres on which they depend. Once seeded with payloads from Earth, further growth in the solar system would not have an impact on the Earth’s biosphere at all. There would no longer be a conflict between human and environmental needs. We could allow the population to rise, fall, or remain steady as we wished based purely on social preference, not under a perceived or real physical constraint.
And an upper limit of harvesting only a thousandths of the sun's energy is extremely conservative.

1. Wanting to live is not hedonism. It is the most basic human drive, and it should not be stigmatized out of an unrealistically pessimistic assessment of humanity's potential combined with a misapprehension that life and prosperity are zero sum, and thus wanting more of them for one's self is immoral.
2. Solving aging is a need for all humanity, not just a few. Almost all medical expenses essentially go to forestalling its effects.
