What's the Name of That Book??? discussion

I remember reading this book in 2022/2023. I hope in the description I won’t be accidentally mixing up books I’ve read before, but I’m 100% sure only of what I said in the topic. I am also quite sure I remember the cover. It was white with I think a hole on it and humans walking around it, everything seen from a perspective above the humans, but from an angle where you could see their body and not only their head. The main character was Macbeth, I think between 40 and 50 years old, and I don’t remember well the genre, but I know that next to the end there was a scene inside an office where he, a woman and another man were in the room, and somehow they stopped being able to see the room, and instead they time traveled. They time traveled back to the past, and they eventually reached the time right after the birth of Earth, and I remember there being a fact about how back then no human could have survived. Then Macbeth woke up and right at the end it was revealed that he was a computer program all along, and that it had failed by dying so they were about to restart it. I’d say it was set for sure in at least 1980, but because of the whole computer program thing it’s probably set in a far more recent year. About the scene I’ll describe now I’m not as sure at all, so possibly don’t rely on it since at the time I used to read 6 books in a row, so I could have easily mistaken this scene when it’s from another book, but I think that at some point someone said there was a bomb about to be exploded either in a Jewish church or in a Mosque. A woman also pretended to join a church, and a mad mad threw himself from the front of the same church, at which point one of the observers [I think Macbeth], including the police, looking from the ground, wondered how it would have been if like Schrödinger’s cat there were a possibility he wouldn’t have jumped down. I also think Macbeth held a lecture and that the place he was in exploded or that many people inside died another way like a shooting, but he was unharmed because right then he had been in the garden [not sure about this detail, but I remember for sure it happened far before the time-travel]

Darry, how would you describe the mood or tone of the story?

I copied a few book details to the topic header. Feel free to edit it.

I’d say it was serious, certainly not comedy or romance or anything written as lightly, but it wasn’t too philosophical either. I think it read like any thriller book, because I remember there being suspense in it, and I haven’t read it in English [it has been translated in Italian, if it helps, because that’s the language I’ve read it in, but I’m almost entirely sure it was from an American or British author], so I can only tell the language was neither complicated nor too simple. Having read it translated is probably a problem here because I remember the title had something to do with the word ‘end’ — maybe ‘close to the end’ or ‘last thing to do before the end’ or it just had the word ‘last’ in it, but that might not have been the original title, so that’s why I didn’t mention it until now. I remember the writing had the most suspense in the part I described where time-travel occurred, but I really can’t remember the exact genre

bump

Biblical maybe? It appears to have matching cover on Italian edition:

Yes, it’s that one! Thank you all, I was going insane, now I finally know what the hell its name is
