plant life, animal species, even the human race...would things be different on earth?

The moon is currently 238,857 miles from earth, so 250 miles would not cause any noticeable change.
Due to centrifugal force, the moon is moving away from earth at about 1.5 inches a year. Based on that speed, the moon was 250 miles closer to Earth a little over 12,000 years ago. There were humans then and the planet was not significantly different than it is now.

well, 250 miles is a really insignificant distance in outer space...don't know if anyone even uses that term anymore.
anyway, the only difference it is likely to have is on the tides and waves. there will probably be slightly stronger currents and more obvious tidal differences between high tides and low tides, but that would be about it.
however, if the moon were to move 250 miles closer, it would mean that the earth's gravity has increased. this is likely to have a far greater effect on life forms on earth than the moon.

Seeing as how the moon started out with a much closer orbit than today, the moon HAS been 250 miles closer to the earth fairly recently, so it's hard to imagine that things would be much different.

We might start to believe that people have been their. Does it seem curious that a flag was planted on the moon but we cannot see it. Looking through a telescope and seeing that might lead people to believe.
Other than that, the tides would probably rise uncontrolably drowning a majority of the earths population.

P2^2/r2^3 = P1^2/r1^3
P2^2 = P1^2(r2/r1)^3
P2^2 = 27.32^2(238,607/238,857)^3
P2 = 27.28
The Moon would have a period of 27.28 days instead of 27.32 days, which is scarcely noticeable. The difference in tide levels would not be very noticeable, either.

well gravity would pull it eventually right now its in the most perfect spot but if it was closer we would all die most likely

the ocean would out control probly more waves than we could handle
