Aliens - Are they out there? Have they visited us? And related questions

[-KT]

Just wondering what peoples opinions are on these closely related subjects. Here are some questions for you to consider and think about:

1. Is there intelligent life outside Earth?
   
2. Have we been visited by beings from other planets?
   
3. Would aliens look like us or carry basic similarities?
   
4. Is the money wasted on looking for life outside of Earth?
   
5. Could or would aliens have a similar society to our own?
   
6. Could or would aliens believe in a 'God' figure or have a religious society?

I believe there is life out there, somewhere. It would be very improbable that in the vastness of space we are all alone, there's something called the Drake Equation . It considers all the factors which should develop intelligent life able to communicate with us within our galaxy. The answer is 10, although just a prediction it's an interesting thought. I do not believe we have been visited by aliens, it is highly unlikely as it would take millions of years to get to the Earth and I believe that their society would be similar to ours, in a way that they are trying to find other life outside their own planet and would most likely make contact. Now the next question starts many an argument between my brother and I, I believe that aliens would look nothing like us as we have evolved to live on this planet. We have evolved in a way which would only suit our environment. This also raises an interesting question as in the Earth we are the only species to develop intelligent life, who's to say it isn't exactly the same on another planet? Next we have money issues, is it really work beaming up signals into space for the off chance we get lucky and find something? SETI spend a lot of money in looking for other life but is it really worth it? Now these next two I can't answer, I would like to think that aliens would have a similar society to ours, it would seem logical, I guess. On the other hand their evolution could lead to a totally different kind of society all together.

Any religious people who want to give their input is welcomed.
