Mesolithic

Bow and arrow were invented about 15,000 years ago, when the last ice age was ending. Before that, people used a stick to make their arm longer, thus enhancing the power with which the spear was thrown...

They surely existed but we are not able to recognize them as such in archaeological material. Miniature vessels, figures of people or animals, rattles and similar artefacts were often made but may have been used for religious and magical activities...

There were no schools yet as nobody could read or write, so no time needed to be wasted on that. Instead, they had to help with jobs in and around the house like cooking, spinning wool and tending the cattle. Surely they had time for play as well. Excavations revealed for example small ceramic pots and animals. Maybe these were toys.

Yes and no. Marbles were used for playing as long as we know of. In Egypt and Pre Colombian America, marbles were used, made of fired clay. Children used whatever material came to hand: polished stones, nuts et cetera...

People in prehistory did not get very old, meaning one had to grow up much earlier. There was less time to remain a child than nowadays. Besides this, life was very hard...

In the Old and Middle Stone Age (in the Netherlands about 250.000 - 7.300 years ago) the people were hunters & gatherers. They hunted for wild animals, but did not keep them themselves...

The Stone Age people died - in respect to present - very early. Poor hygiene, illnesses, bad nourishment and burden of labour lead to an average life expectancy of 20-25 years. Many children already died in their first 4 years...

We have never recovered any prehistoric toilets. When excavating settlements from this period, usually many traces of pits are found, but in most cases it is impossible to see what exactly they were used for, for storage, garbage or something else...

Stone Age takes from 130,000 until 4,200 years before present, or no less then a huge period of 125,800 years. To understand this period better, archaeologists have tried to divide it into different phases, using certain criteria...

There are numerous copied artefacts. It is quite well possible to copy prehistoric objects. For a layman it is especially in the case of flint objects difficult to see the difference between a copy and an original. Archaeologists however can generally speaking discern such "fakes"...
