This is not a question on which we are going to agree. Unless I am very much mistaken, you believe we are meant to be. If so, then everything that has led us to this point must have been designed. It cannot have been an accident of nature. So if you start with that initial proposal - we are meant to be here, then any argument that proposes a random sequence of events isn't going to make any sense.
Conversely, if one believes that we are the lucky winners of a celestial lottery, then any argument re design is going to make as much sense. That is, none.
The odds are only applicable if there is a desired result. A quick story to illustrate.
I was playing poker in a local pub a few years back. My son was playing as well. I got knocked out so I stood at his table to watch him play. On his deal, he dealt three aces on the flop, another on the turn and a king on the river. The odds of doing that are 1 in 250,000,000 (52x51x50x49x48). Everyone was taking pictures. But it only looked amazing because it was already decided that 4 aces and a king were one of the best 5 cards that could have been dealt (a royal flush would have been more impressive). Any random group of five cards you want to nominate will have exactly the same odds of being dealt.
So the odds only matter if the result is a pre determined one. Otherwise...they're just big numbers that don't signify anything.
