Paleozoic Era, also spelled Palaeozoic, major interval of geologic time that began 541 million years ago with the Cambrian explosion, an extraordinary diversification of marine animals, and ended about 252 million years ago with the end-Permian extinction, the greatest extinction event in Earth history. The major divisions of the Paleozoic Era, from oldest to youngest, are the Cambrian (541 million to 485.4 million years ago), Ordovician (485.4 million to 443.8 million years ago), Silurian (443.8 million to 419.2 million years ago), Devonian (419.2 million to 358.9 million years ago), Carboniferous (358.9 million to 298.9 million years ago), and Permian (298.9 million to 252.2 million years ago) periods. The Paleozoic takes its name from the Greek word for ancient life.
Well naturally, the two people should meet in the beginning. They ultimately need to fall in love so your story can later determine if it’s “fate” or just “love” they’re experiencing. If you’ve been in love before, that should help you write. Never answering the question “fate or love” could be cool too. Leave the reader to decide... but that’s more of an ending lol.
You can make the couple meet online, in person, naturally, on accident, literally however. In my opinion a long distance relationship might solidify the question “fate or love” simply because in a LDR (long distance relationship) the two can be so deeply in love, but so far away. This almost forces you to think “is this relationship fate, or are they just in love?” You need conflict definitely. Provoke the mind to ask this question. You can do it!!
