There are two kinds of Nibbana, namely: (i) Nibbana that can be experienced & (ii) Nibbana that is the ending of sense experience which can only be inferred. To quote:
Bhikkhus, there are these two Nibbāna-elements. What are the two? The Nibbāna-element with residue left and the Nibbāna-element with no
What, bhikkhus, is the Nibbāna-element with residue left? Here a bhikkhu is an arahant, one whose taints are destroyed, the holy life
fulfilled, who has done what had to be done, laid down the burden,
attained the goal, destroyed the fetters of being, completely released
through final knowledge (enlightenment). However, his five sense faculties remain
unimpaired, by which he still experiences what is agreeable and
disagreeable and feels pleasure and pain. It is the extinction of
attachment, hate and delusion in him that is called the
Nibbāna-element with residue left.
Now what, bhikkhus, is the Nibbāna-element with no residue left? Here a bhikkhu is an arahant … completely released through final
knowledge. For him, here in this very life, all that is experienced,
not being delighted in, will be extinguished. That, bhikkhus, is
called the Nibbāna-element with no residue left.
The inferred Nibbana cannot occur without experiencing the known enlightened Nibbana.
The Nibbana that can be known occurs after/with enlightenment.
The Nibbana that occurs when a lighted lamp, having taken away the oil and the wick, will not light again, is only inferred & not the primary goal of Buddhism because it cannot occur without the Nibbana of enlightenment.
Just as an oil lamp burns in dependence on oil & wick; and from the termination of the oil & wick — and from not being provided any other
sustenance — it goes out unnourished; even so, when sensing a feeling
limited to the body, one discerns that 'I am sensing a feeling limited
to the body.' When sensing a feeling limited to life, one discerns
that 'I am sensing a feeling limited to life.' One discerns that 'With
the break-up of the body, after the termination of life, all that is
sensed, not being relished, will grow cold right here.'
In summary, the question is inferring there is a destination (i.e. Nibbana) without a path (i.e. enlightenment). The question ignores the special teaching of the Buddha, namely, the Four Noble Truths:
Ete kho, bhikkhave, ubho ante anupagamma majjhimā paṭipadā tathāgatena abhisambuddhā cakkhukaraṇī ñāṇakaraṇī upasamāya abhiññāya
sambodhāya nibbānāya saṃvattati.
A middle path, O bhikkhus avoiding the two extremes, has been discovered by the Tathagata-a path which opens the eyes, and bestows
understanding, which leads to peace of mind, to the higher wisdom, to
full enlightenment, to Nirvana!
That 'sambodhāya' is translated as 'enlightenment' or 'awakening' is irrelevant to the question because the question wrongly assumes 'Nibbana' is darkness, death & annihilation.
