I don't believe there is evidence of life outside Earth, whether past or present. There are indications that life as we know it is/was/might be possible, but no hard and fast evidence.

That said, my point is, while life might be abundant in a universe that permits life to exist, and it would be surprising that no life ever evolved in such circumstances, it seems far more probable that a universe that comes into existence purely by chance will produce conditions that are inimical to all life forms.
