A popular proverb in some circles is the semi-alliterative:
|Absence of evidence is not evidence of absence.|
This is often recited by those who dearly desire to believe in something --- a nefarious plot, a foreign conspiracy, etc. --- in spite of the total lack of supporting facts or observations.
But as a comrade (DD) points out, absence of evidence is certainly not evidence of presence --- even though True Believers might wish it were so!
