Surprised to see the willingness to accept fate, whatever you mean by that, but not karma.
I'm of a scientific bent and believe in a form of karma that naturally occurs in many situations because of purely logical reasons. Eg, someone who's cheated then struggles with trust and suffers as a result.
If your belief basis is scientific then fate also must be true in a sense - from one state of the universe, in the macro scale, the subsequent state a moment later can be predicted (or at least it could if we could know the position and momentum of all particles at any one moment, in the entire universe, and had sussed the link between general relativity and quantum mechanics - but just because we can't now, the assumption is that we could if we knew more and were better at it). Eg, the balls on a snooker table are 'fated' to move a certain way from the moment the white is hit. But there's no scientific basis for there to be some sentience behind the cue! Which some of you seem to be implying.
Any weird happenings you've had are purely coincidence.
Note that a world without coincidences would be WAY weirder are FAR less likely to occur (in a mathematical/scientific sense) than one with.
