Seedlings planted too deep?

I planted my seeds in the ground.. i'm not sure if they we're planted to deep but i planted them a while ago.. aprox 7-8 days ago and i still haven't seen a sign of greenery..

What if i planted them too deep??

Wont they everntually pop out or are they missing out on the sunlight since they we're too deep..

Confused..

Cheers

try carefully scraping the surface to find the seeds, see if they cracked. If they didn't take them out and try the paper towel method... which should really be used regardless since it gives better germination rates. If they did crack sprinkle a little bit of soil over them, .25cm max, unless they are already trying to break out of the seed pod then keep it uncovered.
