Question:
Do you think that there are plants, water,etc. on other planets?
Replies:
There is certainly water on other planets (Mars for example),
but much more is needed for life. Most planetary scientists
believe that life probably existed on Mars sometime in the past
even if there's none there now, but there's no scientific evidence
for life existing anywhere except on Earth. That could change soon
with the new missions to Mars. A separate issue is whether or not
other solar systems exist, and, if they do, do they have planets
capable of supporting life. Since there's no scientific evidence
one way or the other, this is largely a matter of personal belief.
I like to think there is life elsewhere.
