Where did this comet or particle come from that supposedly started all life?
_____________
I do not accept the unlikely idea that life came on a comet/meteor, or the very ridiculous idea that the water on earth had similar origins! There is no essential rationale to suggest this, and, as far as I know, there certainly is no supporting evidence! I expect that an old-fashioned respect for the conditions of the early earth suffice to endow it with everything that we find today! What will they think of next? Can this be just another effort to go against science, like alternative medicine is, or creationism is, for that matter?

Are you telling me that time is circular and has no Beginning?

Time is not a line segment whose endpoints can be connected! Is this what you have in mind? Succeeding time intervals can be represented by successive line segments, directed say, from left to right, or from down to up. But this is just to aid our imagination, primarily for the purpose of using mathematics. Just as the imaginary ‘whole line’ has no end at either extremity, the ‘time line’ need not have, a priori, a beginning or an end! Our time of experience shares an equal conceptual quality with the space of ordinary experience, in classical physics. To Newton, there was no beginning or end of time in his equations of motion, which incidentally, were symmetric in both space and time! Now, what does it mean operationally, that time had a beginning? That there is no time before the beginning! How could we find out, test it that is, if there is no time to experience this absence of time? Do you have an idea of where I have been, where I am now, and what a mess I will be in if I continue with this? Another
