Ok, well here is my many guesses on what this crappy universe is about. First off it is infinite. Remember there are way more dimensions than just 3. We can't observe the others so we quickly conclude that it is finite just because we cant see what lays beyond. And keep in mind that there are infinite parallel universes. Also, life does exist on other planets, we are just too unlucky to be any where near suitable planets for that observation. And imagine this, what if there was another planet in our solar system that is suitable for life? History would be very different, especially if there was life on it. Unforunately humans would have probably erradicated the life on the planet, I say this because we have too much history of taking over native civilizations for greed. (Aztecs, Native Americans, etc.) If, however, humans coexist peacefully with that species (assuming it is intelligent) or there was no race to compete against on the planet, I would imagine we would be years and years ahead of our current technology. That space race we had would have existed longer. Now these are just a small number of guesses I have to what is the truth, and hopefully one day humans can get together to figure it out in oreder to survive. Our time is running out. (Global war with nukes, meteor strike, over population, even hostile alien takeover, lol)
