If each dead person became a ghost, there'd be more than 100 billion of them haunting us all. Creepy, but cool.

Right now people think God is dark energy and dark matter, the spirit. Go ahead and think that, but the day we can tell you exactly what it is - that it's gremlins in the vacuum of space or whatever - then what's your recourse at that point?

I think that intelligence is such a narrow branch of the tree of life - this branch of primates we call humans. No other animal, by our definition, can be considered intelligent. So intelligence can't be all that important for survival, because there are so many animals that don't have what we call intelligence, and they're surviving just fine.

If Mars formed life, then life on Earth could have been seeded by life on Mars, making every life form on Earth descended from Martians.

So maybe part of our formal education should be training in empathy. Imagine how different the world would be if, in fact, that were 'reading, writing, arithmetic, empathy.'

Americans live in a free country, which allows you to believe what you want. Because you think that something is true does not require that it is objectively true. The value of science concerning itself with objective truths is that we can make decisions and statements that affect everyone, which is why legislation really should be based on objective truths, not what is going on in your head.

The persistent failures of controlled, double-blind experiments to support the claims of parapsychology suggest that what's going on is nonsense rather than sixth sense.
