which invention is the most greatest do u think?which one affected us most?

i think the satellite is the greatest one. it makes people know all the news from all the corner of the world. and the satellite have taken lots of photos about lots kinds of subject. it helps us watch the outside space also.

the first thought that came upon me is the god. you know he created the whole world ,he is really great, isn't he? the second i hit upon is the electric bulb.i really can't imagine how can i live without electric bulb, you know i am quite afraid of the darkness and want to stay at the bright place.the third one that i apprricate is the computer. it provides an opportunity for me to have so many kind friends just like you.and it is so convenient for us to gether different information. happy everyday, friend!

The greatest invention everybody to admire with is the tyre by dunlop. Affected mos means viruses and ofcourse aids .

I think it's the reveal of fire...maybe we wouldn't survived without fire ....idk it's my opinion
