If I were God I would make sure that everyone had the pleasure of enjoying the time that they had. Make sure that people still had a conscious. As far as space I think I would try to make space habitable for our human race.

Which god?

Nothing. Absolutely nothing. There can't be significant suffering if I'm the only thing that exists

Like I keep saying, that's already true. We are our own gods, and are contributing to creating our own realities.

Power over time: "For physicists, the distinction between past, present and future is only a stubbornly persistent illusion." -Einstein.

Power for creating our own realities: “Consciousness is fundamental and matter is derived from consciousness." – Max Planck, theoretical physicist who originated quantum theory, 1918 Nobel Prize in Physics

I'd clean up this planet, returning it to the healthy ecosystem it once was. Then, I'd remove each and every one of my ''followers'' who believes in violence, terrorism, prejudice, domination of women AND/OR other followers. Then, I'd remove everyone who stands against women's opportunities for equality. I'd cause infertility for anyone who had more than one child. Then, I'd appear in the sky and warn them that anyone who doesn't play well with others will EVAPORATE...at my pleasure.

(Of course, I'd have to find some truly SPLENDID robes to wear for my appearance...earrings of lightning bolts, a starry crown....that sort of thing. One must make an impression, mustn't one?)
