Honestly, nothing matters.
Humanity probably won't make it past 250 million years. (probably much less since resources will be consumed by the massive numbers of humans on Earth)
The last black holes will evaporate in the year 2 x 10^106 (20,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000) (not counting proton decay which would be an even longer existence of the universe)
Humanity as a whole is only going to exist for 0.12500000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000% (1.25 x 10 ^-98) of the universe's existence.
Most people (living 72 years) are only going to exist for 3.6 x 10^-105 of the universe's existence. (0.36000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000%)
This would be like 1 nanosecond (1 billionth of a second) in 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years.
We're such a small speck of the total timeline.
