noun
smidgen
SMIJ-un/ˈsmɪdʒən/
A very small amount.
Only a smidgen of cinnamon lies in the otherwise empty spoon.

Etymology
Smidgen probably comes from Scots smitch, meaning a very small amount, spot, or mote. The modern meaning retains that emphasis on minuteness: not merely some quantity, but a mere speck.
In context
there is no evidence, not a smidgen of evidence, suggesting life anywhere else.
