The current scientific guess is that amino acids got accumulated in hot springs. Then, with the consecutive wetting and drying up of this semi-organic mud it created protocells that encapsulated these amino acids… and pop! It became a whole living and fully functional cell.
Sure, it might not sound convincing, but (1) from a material point of view, we have nothing better, and (2) we are discovering new hints every day.

To answer this, we need to delve into the field of cosmology. After the big bang, physicists think that particles formed which then became elements and then made the stars and planets when they all smooshed together. Once stars formed, more elements could be made because of the extreme heat in stars which means that fusion can take place, creating heavier elements. Most scientists think that life originated in the oceans of the early Earth and evolved into various other creatures. But the truth is, we don’t really know how life originated, but it’s something that I think we will find the answer to in the future!

Here’s a fun question: did life originate from simple chemicals on Earth, or can life spread between planets? It’s something we don’t really know much about, but some people think life can be passed to other planets on asteroids. There are a lot of problems with this idea – bacteria have to survive in the harsh environment of space for a long time – but it’s not completely impossible.
