It is indeed possible to become enlightened (i.e. attain Nibbana) without becoming a Buddhist and without encountering the teachings of a Sammasambuddha. Such beings are called Pacceka Buddha or Pratyeka Buddha (see here and here), which literally means "private Buddha" or "lone Buddha". You can find some details in this question.

It is also true that Buddhism is very far away from (almost) every other religion, because of Anatta (no eternal self), and also the middle way between eternalism and annihilationism (see this answer).

In MN2, the Buddha states clearly that having the wrong view of an eternal, independent and standalone self is not conducive to attaining Nibbana (permanent happiness and freedom from suffering). If one believes in an Eternal God, then this implies a belief in an eternal self who is the Eternal God, and therefore is also a wrong view, from the Buddhist perspective.

Not everyone becomes a Buddhist, partly because the full depth of the teachings may not be easy for all to understand as the Buddha stated in MN26:

'This Dhamma that I have attained is deep, hard to see, hard to realize, peaceful, refined, beyond the scope of conjecture, subtle, to-be-experienced by the wise. But this generation delights in attachment, is excited by attachment, enjoys attachment. For a generation delighting in attachment, excited by attachment, enjoying attachment, this/that conditionality & dependent co-arising are hard to see. This state, too, is hard to see: the resolution of all fabrications, the relinquishment of all acquisitions, the ending of craving; dispassion; cessation; Unbinding.

To be honest, even for Buddhists, Anatta and dependent origination may be hard to fully understand and realize through their own experience and discernment. For this is needed (along with other things), to attain stream entry.

However, according to Buddhism, every person, regardless Buddhist or non-Buddhist, have the right to impermanent forms of happiness, including the right to be reborn in the heavans.

Christians who practise John 13:34-35 and Hindus who practise BG12.13-14, would be fulfilling the Buddhist practice of the Brahmaviharas (at least one or two of them), which should lead them to heavan (but that would not be permanent).

I once asked a similar question here, where you can find some quotes showing that the description of Nibbana sounds similar to the description of Tao and Brahman/Atma. So, you can also draw some relief from there that there is some degree of overlap, but nevertheless, Anatta is a core part of the teachings and cannot be compromised.
