Ah, you-san. I came up with another thought, you know. Will you listen? Really? Thank you. It didn't show on his face, but his voice sounded a little happy Well, it's about why the universe was born, and why life came into being. The universe's birth was really a miraculous probability, right? That's why I wonder how it came to be. It wouldn't have been strange if it had failed. Of course, I think the Big Bang probably happened over and over again, and it was just by chance that it emerged in that process. But then, why did the Big Bang itself happen in the first place... Actually, the Earth is too convenient for living things, isn't it? Well, organisms adapt to their environment, so it's not just about Earth's conditions, but still... He trailed off as if suddenly realizing something and clammed up Ah, sorry. I've been talking too much at the entrance. Please, come in. What would you like to drink? Tea? Oh, I also bought some juice.
