Is it normal that i love pondering the mysteries of my reality

I love thinking about perplexing things about my own reality. I often ask questions to myself like, why am I concious, why am I me, if I were anyone else, I wouldn't be me. If anything happened differently in my past, I wouldn't be me. Think about it, every little thing that you have ever done, every experience you have ever been through. Is a tiny building block in who you are.

I also find myself pondering how the universe works. If there was a big bang, how did the universe get into that tiny point before the explosion. Was it a previous universe much like ours today. Maybe after trillions of years, all of the black holes caused by star deaths, combined into one, eventually sucking up all matter and focusing it in one singularity, causing some unimaginable events and reactions to occur, ultimately resulting in an explosion, recreating the universe. That's right, the universe could be a cycle of unfolding events that reoccur continuously.

Another thing a recently started thinking about, is how I am a giant structure of around 10 billion individual cells, that form one concious entity. How the hell does that even happen. And where is that fine line that separates the most unsophisticated microorganism from an inaniment machine that has a natural balance to allow continuous, controlled chemical reactions.

Does anyone else love thinking about this stuff, is it normal to you.
