The first eukaryotic cell did not appear until 2.5 billion years ago approximately.  We know this because of the fossil record.  How did those first eukaryotic cells get here?  What are your ideas concerning the evolution of the first eukaryotic cells?  Do not concern yourself with how life first formed, rather just concern yourself with how eukaryotic cells first evolved.  Please look at this from a scientific standpoint and not a religious point of view.

Thank you for the opportunity to help you with your question!

a eukaryote cell begins with a process named endosymbiosis; This is when one prokaryote engulfs a smaller prokaryote that's is respiring. The small prokaryote is then turned into a membrane-bound organelle, Thus the evolution

These theory can be supported when we look at mitochondria and chloroplast evolution. They are formed exactly the same way a eukaryote is formed. Thus, the possibility is more than enough  

Please let me know if you need any clarification. I'm always happy to answer your questions.
