Why do we not see new stars every night when the light from far away stars reach us for the first time? We are not seeing more and more new ones. Why?

Good question. We do occasionally see light from brand "new stars" only they are really old ones, novae and supernovae. Tycho's star, whose light reached us in November 1572, actually left the exploding star centuries or millennia earlier. There is a new star in Orion whose light recently reached us in the 1930s; maybe it is just turning on. But it really lit up 1500 years ago.
