En555 timer create a alternating flashing light

There is so much wrong here I just started from scratch.
First the power supply part looks to have a problem as it causes routing errors. So I started with a blank sketch and used the parts search to search for 555, picked the dip 8 version (which is probably what you actually have) and dragged it in to schematic view. Then I searched for battery and dragged the 9V battery in to schematic. Then a capacitor and used inspector (lower right window) to change the value to 10uf. Then a resistor and again used inspector to change the value to 47k. Then two more resistors left at the default 220 ohms. Then two leds. Which completes the parts. Now in schematic and breadboard views drag the parts til they match this sketch:

Now in schematic connect the capacitor and the 47k resistor, and the two 220 ohm resistors and the leds as shown in this sketch:

bb_align.fzz (4.3 KB)

now switch to breadboard view and look at the lines that
connect the resistors and the leds and the 47k resistor and the capacitor. If yours don’t match the sketch then select that resistor and right click and select rotate 180 degrees til they do match. It is important that the alignment in schematic match that in breadboard. Now connect the rest of the wires in schematic giving sketch

schematic_done.fzz (6.8 KB)

now switch to breadboard and connect and route the light colored lines to match the final sketch;’

complete.fzz (9.9 KB)

and if you wire your real breadboard to match this then the circuit should work.
