I’m genuinely interested when you say you got lucky in the celestial lottery.
One of the things we non-religious have to ponder is the question of who ‘I’ am (and ‘you’ too, for that matter. While it seems obvious that there is an ‘I’ somewhere inside us I don’t really know of any scientific evidence of this. Instead the evidence we have is for the survival over generations of groups at different levels - families, sub-species, species, etc. ‘Individuals’ experience life as if we were real and significant, but looking objectively from the outside it is hard to see the this is the case.
The idea that it can live on, astral travel, be reincarnated or even be joined again to a resurrected body seems (to the religious generally, not just Catholics) to make sense.
Anyway, not expecting you to doubt that ‘you’ are real but most atheists who think about it find it hard to accomodate the sensation of being something more than our body with our non-belief.
Some of us (you @Freddy ?) hold to the unreality of an on-going self, but appreciate the fact that yes, this collection of meat and bones can indeed think, reason, reflect, learn and communicate to a qualitatively different level than other living things (at least those now existing).
The chances that I came into existence depended on everything happening to my ancestors just as it did. If, on the fateful night, my Dad had said to Mum ‘hang on, I forgot to put the cat out’ ‘I’ would never had existed. If any new human being resulted, it would not have been me. A different sperm would have entered the ovum. Maybe even a different ovum. And so on. Things would not have been genetically the same had my Dad not smoked a pipe. Or my Mum been a drinker. Or her Mum, or he great-great-great grandfather, Going back to my primevally slimy ancient ancestor, everything would have had to be just the same for my genetic make-up to be exactly the same.
This understanding of the contingencies that lie behind each human existence is what those us us who talk of celestial latter-winning have in mind.
And even of matter has a tendency to develop into life and has done so many, many times on many-many planets, we know that among the billions of species on earth only one lineage has developed intelligent consciousness. So even of there is life on other planets we have to take the number of planets with life and multiply it by one over the number of species that have ever lived to get a probability of there being other intelligent life.
So not only to we win the lottery by existing as an individual human, we win by being part of a species capable of thinking and making discussion forum posts!
Resolving this by saying ‘there is a God, and He loves me’ is a hypothesis that fits many facts and stops celebration of the lottery. But some of us think of that hypothesis as being without hard evidence.
So we get back to celebrating our win in the cosmic lotto! (Hope that is vaguely understandable!)
