are we alone in the universe?

but we find none, nothing here, only DNA life

now if lifeforms other than DNA based can exist, but they are more complex than DNA, then the probability equations hold true for them. They would be even more unlikely to spring into existance spontainously than we were

so (according to statisics) they are not out there either.

However.... i think certian material made today merit attention. there are materials with a "memory" for their shape. i know it may not merit much at first glance but neither would amino acids to an alien. also if their is life like us than they probably wont be the ambasidors for their kind. look at our robotic research is the human race that far a way from giving birth to a mechanical life. and if so will they have a glowing red light that goes back and forth accross their faces. yes deep questions are these. and in responce to the last post the statment was that we didnt know how amino acids were created not DNA.
