Deep thoughts and questions

I have found myself thinking a lot about the universe at large. What would be our reasoning for believing that we are the only life forms in the universe? I mean, why isn't it possible that other planets have their own life forms inhabiting their worlds, just like we live in ours? And if we can bring ourselves to believe in them, why must they (in our minds) be dangerous? Why can't they be friendly and helpful? I also wonder what they would look like? Could they make themselves look like us? How much more advanced are they or how much more primitive are they than us? What do you think?

I also wonder about things such as space time continuum. What are your thoughts on this concept? Do you think it is possible?

What exactly is happening when we have deja vu moments? I would love to hear everyone's thoughts on this. Don't hold back. I am very open minded.

Do you think that if we desire something with all our hearts and do not have any doubt at all, but complete faith that we will have it, that it will be ours? How does one achieve having the 'faith of a mustard seed'? Just that small amount of faith is supposed to be able to move mountains.

Thanks for reading these thoughts of mine, and I hope that you will respond with some thoughts of your own. I would love to hear what you think.
