We wouldnt need to eat eliminating the compliacations of the digestive system.

I'm gonna just keep posting this until it sticks:
Here we go with the correct but still unpopular answer.
In order for evolution to proceed you need genetic variation that is acted upon by natural selection. Natural selection dictates that less fit individuals will reproduce less (or not at all) than more fit individuals. Without natural selection THERE IS NO EVOLUTION.
So, if you look at human beings, we've had the technology for centuries to assure that all humans (or at least a random sampling) reach adult reproductive age, regardless of fitness (those 6 billion people out there must be proof of that). Hence there is no natural selection in human populations, hence there is no evolution in human populations.
Human technologies may evolve, but humans as a species have stopped undergoing biological evolution long ago.

Hmm! So, you are saying that evolution is directed towards self-sustained humans! Interesting! But there is no indications of that still yet.
Well, if we assume, for the present context at least, that that may happen. Then one should remember that such a drastic change in metabolism needs a big environmental influence. Hope i am not confusing you. I mean, a sitution have to be arised when natural photosynthetic plants will not be there. Then only the body will meet the biological demand to be evolved in such a way. But, considering the amount of change needed, i suspect human being will be eleminated before that evolution could have taken place.

God designed humans to be omnivorous. We can eat almost anything and survive. If we used the sun for energy what would we do at night? To power an organism as large as a human takes a tremendous amount of calories. Solar power through photosynthesis is not very good. That is why we gain lots of weight when we eat lots of meat. We would have to be very small if we were to continue moving at the same pace we are now.

We'd all be green then ;) Loaded with Chlorophyll.
Seriously, the sun could supply us all with energy by converting light to electricity. This can be done today but very inefficiently. As battery technology improves (small, lighter, longer) and the conversion efficiency improves (light to electricity) the sun could be more fully harnessed to replace oil, coal, nuclear fuels. And we could carry the power around in efficient batteries.

convinced, I settle for this. Its how issues artwork, species come and species bypass. The solar will die in 5 billion years, which skill we would in trouble-free words have about 5 billions years to stay. yet to allow you to recognize the reality, the human race would wipe itself out in the subsequent a million,000 years. there are this style of number of wars, and mess ups, and diseases and so on.... regardless of if we are alive a million billion years from now, the solar is increasing, and a million billion years from now, Earth receives hotter. And in 2 billion years, our oceans will maximum in all probability boil away. Sow e have lower than 2 billion years to get our act jointly. in trouble-free words issues that would keep our species is to comprehend interstellar go back and forth, to flow to an finished different photo voltaic equipment. And in a million billion years (if we are residing to inform the tale that lengthy) the human race will likely we stepped ahead sufficient to bypass to different photo voltaic structures. yet when we dont live to inform the tale, thats ok, anybody has to bypass some day.

It's possible, we do have a lot of solar powered stuff available.
As far as the eating goes though; No you still need to eat. The sun will not give us nutrients, our bodies need nutrients,

Autotrophic photosynthesis works better for plants than it does for animals. Movement tends to require an awful lot of energy.

If we developped to a point where we efficiently used ligth from the sun then, maybe. but i think we would be black not green because that would mean that we would absorb all light and that would be more effective than plants

Well, The Bible says all we need is th power of The Son, so I suppose anything is possible
