OMG lol at the lanterns, my mate said today that he lit a load the other night in celebratiion of a mates death - I said 'wonder if that is what that bloke saw'

No chance we are alone with the millions and billions of galaxies out there, the odds that we are the only planet with the right conditions to form life are to great.

I never get why people say 'if there is they would be far more advanced and would have contacted us?

Why, they may be no more advanced or less advanced or more, either way they may like us have not yet achieved the ability to cross the vast distances of space, it may even be impossible.
