"Secular scientists believe that the structure and evolution of the solar system have been shaped by stellar flybys—the nearby passage of another star.

---Yet mathematical modelling by a team of scientists has suggested that one of these flybys could destabilize the whole system, as the perturbation to one outer planet would have a knock-on effect to all others. E.g., if Neptune’s semimajor axis were disturbed by only 0.1 %, then the probability of destabilizing the whole system would increase tenfold over 5 billion years (the naturalistic age assigned to the solar system).
This is a major problem for naturalistic scenarios."
