Why did it take over a billion years for living organisms to appear after the earth was formed?

Current estimates are that life emerged on Earth between 3.5 and 3.8 billion years ago, but it may have emerged even earlier than that.
Life, according to our best hypotheses, emerged almost as soon as the conditions were favourable. Before that, the planet's surface was simply too hot, its atmosphere and surface conditions too corrosive. After all, the planet was still cooling down and outgassing following its coalescence from interplanetary debris.

∙ 8y agoThe latest evidence suggests it took less than a billion years for life to first appear, though it still took a few hundred million years. Prior to that Earth was either too hot or two frequently hit by giant asteroids for life to gain a foothold.

Where were the first organic compounds on earth probably formed?
Probably 4 billion years (out of 4.5 billion total), but the simplest ones don't leave much of a record. ------------------------------------------------------------------------------------------------------------- Simple organic compounds can be seen is space dust in distant nebulae, an are to be found in certain (contrite) meteorites which formed in the planetary nebular from which the earth condensed.
