  The present study is devoted to the possibility that tri-atomic molecules
were formed during or shortly after the Big Bang. For this purpose we consider
the ordinary $H_3^{+}$ and $H_3$ and the primitive tri-atomic molecular system,
$H_3^{++}$, which, as is shown, behaves differently. The study is carried out
by comparing the topological features of these systems as they are reflected
through their non-adiabatic coupling terms. Although the $H_3^{++}$ is not
known to exist as a molecule, we found that it behaves as such at intermediate
distances. However this illusion breaks down as its asymptotic region is
reached. Our study indicates that whereas $H_3^{+}$ and $H_3$ dissociate
smoothly, the $H_3^{++}$, does not seem to do so. Nevertheless, the fact that
$H_3^{++}$ is capable of living as a molecule on borrowed time enables it to
catch an electron and form a molecule via the reaction $H_3^{++} + e \to
H_3^{+}$ that may dissociate properly: $H_3^{+} \to H^{+} + H_2$ or $H +
H_2^+$. Thus, the two unique features acquired by $H_3^{++}$ namely, that it is
the most primitive system formed by three protons and one electron and
topologically, still remain for an instant a molecule, may make it the sole
candidate for becoming the \bold{cornerstone} for creating the molecules.
