Can you be 100% sure there is not an invisible pot of flowers in space that we cannot detect?
Didn't the astronauts and cosmonauts on the International Space Station witness around 15 sunrises and 15 sunsets every 24 hours?
Is it an illusion to "see" sunrise? Seeing is a perception and seeing the sunrise is a perception. Astronauts have a different perception than Earth bound travelers.
What is being seen is not an illusion. Perceptions don't lie. They tell exactly what is there. That it represents the up-going and down-going motion of the sun is the illusion, instead of the real spinning of the Earth. From Earth, the sun coming from below and going back down is the illusion that Craig talks about, not that we can see evidence of the movement of our planet in relation to the sun. I'm sure from space, it looks a lot less illusory.
What do you mean, seeing 15 sunrises is an illusion? Did they not see the sun rise over the Earth 15 times? Perception is standpoint specific. It depends upon where you stand as to what you see.
Standing on Earth, I see one sunrise a day.
Standing on a spaceship, I see as many sunrises as the ship circles the Earth.
yes, not to slight the OP's question... but I think this is a better one.
to answer the question...
I cant be 100% sure there is no god... But I 100% DO NOT BELIEVE there is a god... if that makes any sense.
